Oracle of Mul-Daya and Zoetic Cavern

I have Oracle of Mul-Daya in play and draw my card for the turn. On top of the library is a Zoetic Cavern. 2 questions for this and please quote specific rules when answering. TY in advance.

1. Can I play the Cavern as a creature?
2. If so does it count for the land for the turn?

Again...TY in advance.
1. Can I play the Cavern as a creature?

No.

When casting a morph card, you've got to do the following things in order. First, you turn it face down and it is now a 2/2 creature. Then, you determine whether you are allowed to cast that 2/2 creature, and third, if you're allowed to cast it, you do so for .

So when you do this with a zoetic cavern on top of your library, you turn it face down and ask "can i cast this creature from the top of my library"? The answer to that is no. Oracle of mul-daya only allows you to play lands from the top of your library, and the card is no longer a land.
Rulebook Quote
702.34b To cast a card using its morph ability, turn it face down. It becomes a 2/2 face-down creature card, with no text, no name, no subtypes, no expansion symbol, and no mana cost. Any effects or prohibitions that would apply to casting a card with these characteristics (and not the face-up card's characteristics) are applied to casting this card. These values are the copiable values of that object's characteristics. (See rule 613, "Interaction of Continuous Effects," and rule 706, "Copying Objects.") Put it onto the stack (as a face-down spell with the same characteristics), and pay {3} rather than pay its mana cost. This follows the rules for paying alternative costs. You can use morph to cast a card from any zone from which you could normally play it. When the spell resolves, it enters the battlefield with the same characteristics the spell had. The morph effect applies to the face-down object wherever it is, and it ends when the permanent is turned face up.

2. If so does it count for the land for the turn?

If it were legal to cast it face down (for example if we were using Future Sight instead of Oracle of mul-daya) then it would not count as playing land for the turn, because it isn't being played as a land. Playing a land follows a different process than casting a creature.
[sblock=Rulebook Quote]If you're playing a land face down, you use 702.34b, quoted above. Otherwise, you use the following rule:

701.10a To play a land means to put it onto the battlefield from the zone it's in (usually the hand). A player may play a land if he or she has priority, it's the main phase of his or her turn, the stack is empty, and he or she hasn't yet played a land this turn. Playing a land is a special action (see rule 115), so it doesn't use the stack; it simply happens. Putting a land onto the battlefield as the result of a spell or ability isn't the same as playing a land. See rule 305, "Lands."

You must play it as a land.
It will count as one of your land drops. You will still have one left.
Morph is a static ability that functions in any zone from which you could play the card. If you turn it face down first...it is in the zone that playing cards are in and no longer on the deck. The restrictions it refers to are that of casting the spell. (Gloom, time frame, Aether Storm) No-longer being in the library and not the top card of your library removes the fact that it is now a creature being placed on the stack.

601.2 - To cast a spell is to take it from the zone it's in (usually the hand), put it on the stack, and pay its costs, so that it will eventually resolve and have its effect.

Re-read the Morph rules that cyphern so nicely quoted for you:
702.34b To cast a card using its morph ability, turn it face down. It becomes a 2/2 face-down creature card, with no text, no name, no subtypes, no expansion symbol, and no mana cost. Any effects or prohibitions that would apply to casting a card with these characteristics (and not the face-up card's characteristics) are applied to casting this card. These values are the copiable values of that object's characteristics. (See rule 613, "Interaction of Continuous Effects," and rule 706, "Copying Objects.")

You can use morph to cast a card from any zone from which you could normally play it. When the spell resolves, it enters the battlefield with the same characteristics the spell had. The morph effect applies to the face-down object wherever it is, and it ends when the permanent is turned face up.

You turn it face-down in the zone it's in before putting it onto the stack,

There are no effects or prohibitions that effect a face down creature on top of your library.

So.....also you must realise...The rule states:To cast a card using its morph ability, turn it face down.

Turning the card face down is the first part of casting it. Once you turn it face down your ARE casting it. Since you ARE casting it and there are NO restrictions or effects tied to this card(Other than it was face down but must remain face up)...it comes down.
There are no effects [...] that [a]ffect a face down creature on top of your library.



Right.  And since there are no rules or effects that allow you to cast a creature from your library, then you can't do it, even though nothing specifically prohibits it, either.

You are already casting the creature when it gets to that point.

Morph does not care what zone it is in once you have started the casting process.

The rules for casting spells do not completely describe the issue of checking the legality of casting spells.  To check if it's legal to cast something, generate a hypothetical mirror of the game, begin to cast the corresponding object in that mirror of the game, and then check if it would be legal to cast that object in that mirror of the game.
So.....also you must realise...The rule states:To cast a card using its morph ability, turn it face down.

Read that as "In order to cast a card via morph, turn it face-down first, then cast it, if able".

Turning the card face down is the first part of casting it. Once you turn it face down your ARE casting it. 

No. You turn it face-down before you start casting it. The turning face-down is not part of casting the card, it is a prerequisite to casting it.

If that were so it would state "In order to cast a card via morph, turn it face-down first, then cast it, if able".
It does not.
If that were so it would state "In order to cast a card via morph, turn it face-down first, then cast it, if able".



Basically, that's exactly what it says:

«Any effects or prohibitions that would apply to casting a card with these characteristics (and not the face-up card’s characteristics) are applied to casting this card.»

If I steal a hundred dollar from a loot of one thousand, people might notice;

If I steal a hundred dollar from a loot of one million, I might get away with it;

If I wish to steal even more and still go unnoticed, I need to make the loot bigger.

 

Now you know why taxes always go up.

 

Looting: ''the plundering of public assets by corrupt or greedy authorities'' (Wikipedia)


You are already casting the creature when it gets to that point.

Morph does not care what zone it is in once you have started the casting process.




Even if what you said was true, you aren't casting the land. You can't cast a land. You play it. Playing a land is a special action who do not use the stack.

So no.

Edit : Rules quote :

Show



115.2a Playing a land is a special action. To play a land, a player puts that land onto the battlefield 
from the zone it was in (usually that player's hand). A player can take this action any time he or
she has priority and the stack is empty during a main phase of his or her turn, but only if he or she
hasn't yet played a land that turn. See rule 305, "Lands."

 


Ps : How do you guys quote a rule? I manually have to edit it...

How do people think saving room to print more abilities on cards is dumbing down the game?

Do you really think, say, Akroma would ever be printed if she said, "Akroma can block by creatures with this ability and cannot be blocked by creatures without this ability.  If a creature without this ability would deal combat damage by Akroma would be destroyed, prevent all combat damage that creature would deal to Akroma this combat.  Attacking does not cause Akroma to tap.  If Akroma is blocked and deals lethal damage, it deals the remainder of its damage to the defending player.  Akroma may attack and use abilities that require tapping in the casting cost the turn it enters the battlefield.  Akroma cannot be damaged, enchanted, equipped, blocked or targeted by black or red sources" rather than her "dumbed down" wording she has?  No freaking way.  Keywording and shorthand allows them to make complicated cards easy to play with, allowing them to be printed in the first place.

6. during their turn, play every permanent in their hand (playing lands with fastbond) then (as yourself) cast mirrorweave on the blacker lotus, so every permanent becomes a copy of it. proceed to tear up every card they control, and hopefully do it before they notice that they aren't bound by staying power's ability anymore and can concede

Everyone's life would be easier if players would, instead of coming to the 'net for help with a deck, just netdeck and be done with it. And I'm not talking about some Top 8 lists, for the Casualists, too, can benefit from netdecking. I've netdecked plenty of decks from the Casual Play forums from users such as Mown, Raedien, Floopfoot, and a few others. I snatched straight the heck out of my web browser. Yes, people, your original idea fell victim to a savage netdecker. You have been assimiliated. Suppose I wanted a Zombie deck. Why on earth would I spend time searching Gatherer for a decent list of Zombie cards when Raedien already did it for me? Taking time to be creative or waiting on people on the forums to tell you why your deck sucks or 'go to Casual forums' is a disasterous waste of time (to me).

This flow, sometimes called convection, is cited by frustrated box mappers as one of WOTC's most genious uses of thermodynamics since the Ravnica block. No one knows what lies at the core of the booster box, but scientists theorize that it must be especially dense in order to make up for the large amount of fluff distributed amongst the booster packs.

Afterwards, he goes to make sure that the good cards are only opened by everyone's friends, and that we all only get to open bad cards. He does this by memorising each booster, than switching them around accordingly.

From the game's perspective, the card can move instantly from face down in the library to revealed in the hand and that's fine for the rules. But in real life, we can't actually do that, so the card spends a good bit of time in locations that are neither where that player's library is nor where that player's hand is. And that's fine for real life. What I don't want is the disconnect to be explicitly codified. Along the lines of

Yeah. Talk to the cashier. Tell him/her that you want a Black Lotus, and if they don't have one tell them that the store isn't on par with what you expected.

 

Reach into your back left pocket. Pull out a deck list that you copied directly from some ChannelFireball top 8 Standard discussion, and ask for all the cards, as is, on that list. Then, ask for some random, probably terrible cards from whatever set is Standard legal. Say it's tech for the upcoming changes in the metagame.

 

Pull out a deck, and tell some random dude you wanna test (you have to use the term "test" for this to work) for Standard. Make sure that deck contains Kitchen Finks and Alluring Siren. Maybe throw in Nyxathid for good measure.

 

Finally, before you leave, spill (make it look like an accident) one hundred singleton, random cards onto the floor. Pick them up, put them in a pile, and say "EEE-DEE-AYCH".

 

I know this sounds dumb at first, but it will work. With the method outlined above, you will draw the attention of players that play older formats by asking for cards that no one on Earth can reasonably afford. You will get the attention of the wanna-be pro, Stomp-n00bz players by pulling out a well known decklist and declare that you have "tech" to make it better. You will get the attention of all the kind, helpful players by seemingly not knowing the most common format by having non-Standard legal cards in a deck that you claim is Standard legal. Finally, you catch all the rest of the Magic players by saying "EEE-DEE-AYCH" (EDH (or Commander)).

And there you have it. You will be talking to more people than you would have wanted to talk to in no time.

If that were so it would state "In order to cast a card via morph, turn it face-down first, then cast it, if able".



Basically, that's exactly what it says:

«Any effects or prohibitions that would apply to casting a card with these characteristics (and not the face-up card’s characteristics) are applied to casting this card.»




We already discussed that there are no prohibitions or effects stopping you from playing  a creature at that point.
We already discussed that there are no prohibitions or effects stopping you from playing  a creature at that point.

True. However, there is nothing allowing you to cast a creature card off of your library, so you can't.

By your logic, does Teferi, Mage of Zhalfir allow me to cast Zoetic Cavern as a face-down creature spell on my opponent's turn? I expect your answer to be "no", because apparently you're arguing that I need to begin the casting process while it's still a land, which I can't do, since Teferi says nothing about lands. (Hint: The correct answer is "yes".)

turn it face-down first,
turn it face down.

then cast it,
Put it onto the stack...

if able
Any effects or prohibitions that would apply to casting a card with these characteristics are applied to casting this card.



702.34b To cast a card using its morph ability, turn it face down. It becomes a 2/2 face-down creature card, with no text, no name, no subtypes, no expansion symbol, and no mana cost.  Any effects or prohibitions that would apply to casting a card with these characteristics (and not the face-up card’s characteristics) are applied to casting this card. These values are the copiable values of that object’s characteristics. Put it onto the stack...



What more could you ask for?

If I steal a hundred dollar from a loot of one thousand, people might notice;

If I steal a hundred dollar from a loot of one million, I might get away with it;

If I wish to steal even more and still go unnoticed, I need to make the loot bigger.

 

Now you know why taxes always go up.

Right and morph says you may use the ability any time you could play the card.

Look at this in two other ways:


You say it is because of the zone that it is in. Well Morph goes around that by stating whenever you could play this card you may morph it and play it. It HAS an added effect. In the totem of what it ask you to do is turn a card in your library upside down. Something that you also can not normally do. Even attempting to do so would break the normal rules. That is where the morph abillity over rides the rules. It says if you could do this you may do this. The second this is play it as a 2/2 creature from the zone it is in.

We weren't talking about having played any lands at all. Just the abillity to morph the card.

Morph allows you to turn the card before casting it.

It then becomes a creature card.

Does Teferi allow you to cast creature cards from your lib-top? No.

Therefore, you're not even allowed to try to cast it under Morph.



Turning the card then becomes an illegal move, so you can't even do that.

(It is an illegal move because it is the first part of the process of casting it under Morph, which you are not allowed to do)

 

601.5. A player can’t begin to cast a spell that’s prohibited from being cast.

If I steal a hundred dollar from a loot of one million, I might get away with it;

True, but his point is accurate: If you've already used all your land-drops for the turn, you can still morph-cast the Cavern. Under your logic, such would not be possible.

In this particular case, "to cast..." means "in order to cast." First you flip it face-down into a 2/2, nameless, colorless creature, then you check for any effects that affect whether or not you can play it. If you can't play it then, it goes back to being "face-up" (but if it was in a hidden zone and only you could see it, that remains true afterward); if you can play it then, you then proceed to actually cast it. They do this because, otherwise, some effects wouldn't work with morph, even though morph is supposed to be the process of casting a creature from start to end. 
MTG Rules Advisor Mirrodin_Loyalty.png

Well Morph goes around that by stating whenever you could play this card you may morph it and play it.

Indeed, if you are allowed to play the card, you are allowed to play it face down, so we need to determine whether you are allowed to play the card or not. You are saying that we should use the face up characteristics of the card (a land) to determine whether we can start casting it. While i don't see any support for that in the rules, let's assume its true and examine the impossible situations this would put us in:

For example: My opponent has Steel Golem on the battlefield. From his hand (which i cannot see), he casts a face down creature. Naturally, i point out to him that steel golem doesn't allow him to cast creatures. He says "oh, don't worry, it's not a creature". I cannot possibly verify that, and he is under no obligation to reveal what the face up version of the card is.

Fortunately, what you are saying is completely wrong, and is explicitly addressed in the rules that have been quoted for you several times: "Any effects or prohibitions that would apply to casting a card with these characteristics (and not the face-up card’s characteristics) are applied to casting this card". You use the face down characteristics to determine whether the spell can be played. If it can not, then the rules for handling illegal actions kick in, and you back up to just before you started casting the spell. How many effects in your scenario allow you to cast creatures from the top of your library? None, and similarly there are no rules that allow it. Therefore, you cannot cast it.

Handling Illegal Actions
715. Handling Illegal Actions

715.1. If a player realizes that he or she can't legally take an action after starting to do so, the entire action is reversed and any payments already made are canceled. No abilities trigger and no effects apply as a result of an undone action. If the action was casting a spell, the spell returns to the zone it came from. The player may also reverse any legal mana abilities activated while making the illegal play, unless mana from them or from any triggered mana abilities they triggered was spent on another mana ability that wasn't reversed. Players may not reverse actions that moved cards to a library, moved cards from a library to any zone other than the stack, or caused a library to be shuffled.
Well Morph goes around that by stating whenever you could play this card you may morph it and play it.

You are saying that we should use the face up characteristics of the card (a land) to determine whether we can start casting it, then we turn it face down, giving it its new characteristics (a creature), and then we continue casting it, even if casting creatures is prohibited. If this were true, then it would lead to situations which are impossible to verify.

For example: My opponent has Steel Golem on the battlefield. From his hand (which i cannot see), he casts a face down creature. Naturally, i point out to him that steel golem doesn't allow him to cast creatures. He says "oh, don't worry, it's not a creature".

There is nothing that says you CAN'T play it once you start the process. That is what allows you the abillity to cast it from other zones and is why they stated "any zone from which you could play the card it's on"
Just to be clear...Not anything with morph would work. You can't morph a  creature off the top because there isn't anything that gives you the abillity to play that card that morph is printed on.
There is nothing that says you CAN'T play it once you start the process. That is what allows you the abillity to cast it from other zones and is why they stated "any zone from which you could play the card it's on"


So what? The rules of Magic say what is allowed to happen. It's unusual, and in all cases I can think of redundant, for them to say what isn't. "It doesn't say you can't" logic is just not applicable. The moment you find yourself saying "There is nothing that says you CAN'T" anything, just stop. With only that information, I can tell you 100% for certain that your logic is wrong, even if your final conclusion is right (which, in this case, it clearly isn't).


(On a totally different note, if you started out unalterably convinced that you already knew the answer to this question, as appears to be the case, why did you ask it to begin with?)
Jeff Heikkinen DCI Rules Advisor since Dec 25, 2011
There is nothing that says you CAN'T play it once you start the process

What's that got to do with anything? There is nothing saying that i cannot cast a sorcery during the resolution of a spell. Absolutely nothing. There is nothing saying i cannot cast spells between the assigning and dealing of combat damage. There is nothing saying that i cannot gain 20 life on a whim. And despite all that, those are all impossible under normal circumstance. Why? Because there is nothing saying I can do them.

You don't need to show that there is nothing prohibiting playing it. You need to show that there is something permitting it.



  • Why can you cast sorceries during your main phase when the stack is empty and you have priority? Because a rule explicitly says you can.

  • Why can you cast instants any time you have priority? Because a rule says you can

  • Why can you cast Benalish Knight any time you have priority? Because the text on the card, in conjunction with the rules that define "flash" says you can.

  • Why can you play a land from the top of the library while Oracle of mul daya is on the battlefield? Because the effect of the oracle says you can.

  • There is no effect saying you can cast a creature from the top of your library. You yourself admitted this in post #7 when you said: "There are no effects or prohibitions that effect (sic) a face down creature on top of your library"

OK...Say you do start the process.

You flip the card over. What rule now states that you can not play it. What exactly is saying that it CAN'T be played? I see morph saying it Can be played. 

702.34a - Morph is a static ability that functions in any zone from which you could play the card it's on, and the morph effect works any time the card is face down. "Morph <-cost->" means "You may cast this card as a 2/2 face-down creature, with no text, no name, no subtypes, no expansion symbol, and no mana cost by paying {3} rather than paying its mana cost."

Once you decide to use the morph abillity you turn it face down to play it. Then you check for any prohibitions or effects.(Zone is no-longer an issue as you have already started the process. You are starting to play it and are now checking for the legality of it. Does anything say you can't play this creature right now? No. They were very clear in naming what would stop it at this point and that is two things. prohibitions or effects.)

I would also like to point out the red text. It works any time the card is face down. Once you have it turned face down on top of your library it states "You may cast this card as a 2/2 face-down creature" it does not state from where it is being played...and has those chariteristics.
You flip the card over. What rule now states that you can not play it. What exactly is saying that it CAN'T be played?

Nothing is saying you can't, but that is completely irrelevant. All that is important is whether something is saying you can.
702.34a - Morph is a static ability that functions in any zone from which you could play the card it's on, and the morph effect works any time the card is face down. 

Why are you highlighting that? That has nothing to do with casting a morph, that has to do with what happens once it is face down. That is the effect that sets its characteristics to be a 2/2 creature with no name, text, subtypes, etc. What you need to look at is the rules for casting morphs, which brings us to the rule that we have quoted for you numerous times, 702.34b.
Once you decide to use the morph abillity you turn it face down to play it. Then you check for any prohibitions or effects.

Correct, and what you are looking for is an effect that allows you to cast it. Stop getting hung up on the word "prohibitions". That is not the only important word in the sentence.

Two answers for ya

1. The red applys to what I say in the last line.(Which I will repeat below.)
2. What allows you to cast it is the morph abillity once it is turned face down.

I would also like to point out the red text. It works any time the card is face down. Once you have it turned face down on top of your library it states "You may cast this card as a 2/2 face-down creature" it does not state from where it is being played...and has those charicteristics
702.34a does not describe how to cast a morph. It describes what zones the morph ability works in, what circumstances the morph effect works under (the morph effect sets the characteristics of the card; it does not dictate the process for casting it), and it gives a broad strokes overview of what the ability does. Since morph is a complicated rule, it then relies on subsequent rules to describe in detail the things it alluded to in its overview. In particular, 702.34b is the rule that addresses casting the morph, and it is that rule you should be turning to.

If you insist on focusing on irrelevant rules, I will no longer be responding to this thread, as I know from past experience that responding would be unproductive.
The rules for casting spells do not completely describe the issue of checking the legality of casting spells.  To check if it's legal to cast something, generate a hypothetical mirror of the game, begin to cast the corresponding object in that mirror of the game, and then check if it would be legal to cast that object in that mirror of the game.


Pickman620: the CR does not adequately address this point, but it does work as everyone here has been saying (based on official rulings).  I agree that it's dumb that the CR doesn't say that, and it should be fixed, but that doesn't mean that it doesn't work as described.

Aside
Where's the rule that says one can cast spells from one's hand?  I'm looking and can't find it.

Edit: Also, where's the rule that prevents one from casting spells from other zones unless something is giving one permission to cast that thing from that place?

It depends on the type of spell.

For example, here is the rule that says you can cast artifact cards from your hand.

301.1. A player who has priority may cast an artifact card from his or her hand during a main phase of his or her turn when the stack is empty. Casting an artifact as a spell uses the stack. (See rule 601, “Casting Spells.” )

There is no rule that says you can normally cast a artifact from your graveyard, so you can't, unless another rule or effect allows it.


Ok, I didn't think to look next to the card types, but, in hindsight, that's a reasonable place to put that kind of rule.  However, in the face of sweeping permissions like I've highlighted below, restrictions need to be in place; a policy of using the lack of permission to approximate a restriction works if and only if permissions are always limited to things that are meant to be allowed.


116.1. Unless a spell or ability is instructing a player to take an action, which player can take actions at any given time is determined by a system of priority. The player with priority may cast spells, activate abilities, and take special actions.


503. Upkeep Step

503.1. First, any abilities that trigger at the beginning of the upkeep step and any abilities that triggered during the turn's untap step go on the stack. (See rule 603, "Handling Triggered Abilities.")

503.2. Second, the active player gets priority. Players may cast spells and activate abilities.


Based on either of these, unless there's a restriction elsewhere, I can clearly cast spells and activate abilities whenever I have priority (including Sorceries) or whenever I want during the Upkeep Step after triggered abilities are put on the stack (even while my opponent is trying to cast a spell).  (And there are, of course, similar statements in the descriptions of all the other steps in which players get priority.)  Unless someone can reference such a restriction, I think this is an issue for RT&T.

The rules are written using an exception-based philosophy. (They work a lot like D&D 3.5 in that respect.)

Under this sort of philosophy, you can categorise rules as general, specific and exceptions. Where a general rule and a specific rule cover the same sort of area, the specific rules supersede that of the general rule. An exception rule supersedes otherwise-applicable general or specific rules.

116.1 is a general rule - it describes the broad, overarching rules for how to cast spells of any type. 301.1 is a specific rule for casting spells with the Artifact type. Therefore the specific rule has the final say.

The specific rules for casting spells of other types also have the final say when a spell of that type is involved.

Exception rules tend to be found on cards.

It might also be beneficial to take a quick look at 601.2.
601.2. To cast a spell is to take it from where it is (usually the hand), put it on the stack, and pay its costs, so that it will eventually resolve and have its effect.

(snip)

601.2a The player announces that he or she is casting the spell. That card (or that copy of a card) moves from where it is to the stack. It becomes the topmost object on the stack. It has all the characteristics of the card (or the copy of a card) associated with it, and that player becomes its controller. The spell remains on the stack until it’s countered, it resolves, or an effect moves it elsewhere.

602.1 doesn't restrict spellcasting to be from the hand; it clearly contemplates casting spells from other zones. However, that doesn't mean it gives permission to cast spells from other zones. It gives no permission to cast spells from anywhere. To get permmission to cast a spell in hand, you refer to the type-specific permits. Permission to cast from graveyard, exile or library generally comes from effects.

So does Morph create an effect that allows the casting of a spell from the library?

The relevant piece of the Morph rule is this.
Any effects or prohibitions that would apply to casting a card with these characteristics (and not the face-up card’s characteristics) are applied to casting this card.

What this (in conjunction with the rules on spellcasting) means is that is that after you have turned the card face-down, you ask yourself "Do I have permission to cast a creature card from the top of my library?"

With the situation as described, the answer is "no." Sure, the Oracle gives permission to play a land, but that doesn't apply to the new situation since the card on top of the library is no longer a land. And if i was, you could not cast it, because lands are never cast.
305.9. If an object is both a land and another card type, it can be played only as a land. It can’t be cast as a spell.

Since you have no permission to cast a spell from the top of your library, you cannot cast a spell from the top of your library.

Nitpick:

For example: My opponent has Steel Golem on the battlefield. From his hand (which i cannot see), he casts a face down creature. Naturally, i point out to him that steel golem doesn't allow him to cast creatures. He says "oh, don't worry, it's not a creature". I cannot possibly verify that, and he is under no obligation to reveal what the face up version of the card is.



Although we both agree on the main subject, I feel I must point out a glitch in your example:

«707.9. If a face-down permanent moves from the battlefield to any other zone, its owner must reveal it to all players as he or she moves it. If a face-down spell moves from the stack to any zone other than the battlefield, its owner must reveal it to all players as he or she moves it. At the end of each game, all face-down permanents and spells must be revealed to all players.»


ANYTIME someone plays a card face-down, he may pretend  "oh, don't worry, it has Morph", and I have to accept it as true... but it has to be revealed some time later, before he may be declared Winner.

(But you were correct otherwise, of course: he CAN'T cast a Morphed card if he controls Steel Golem)

If I steal a hundred dollar from a loot of one thousand, people might notice;

If I steal a hundred dollar from a loot of one million, I might get away with it;

If I wish to steal even more and still go unnoticed, I need to make the loot bigger.

 

Now you know why taxes always go up.

What exactly is saying that it CAN'T be played?



Please refrain from this type of argument. There is no rule stating you can't take out a gun and hold it to your opponent's head until he concedes, but there's nothing permitting that, either.


As has been pointed out to you, the rule you are citing refers to the ability to pay the Morph cost and turn the permanent face-up, not to casting the face-down creature.

There's also no rule stating you CAN'T shred opponent's cards to piece when you feel they're too strong.

Still, you can't. (well, you can, but you'll lose the game... and get in serious trouble!)

Rules state what you CAN do.
Some (redundant) rules state things you CAN'T do, to make it very clear for some blurry situations.

Still, you can do ONLY what the rules state you CAN. Nothing else!

And you cannot take ONE ISOLATED rule to pretend you can do such and such: you need to take into account OTHER rules which may give precision on what/when/where you can do such and such.

The first sentence of the Morph Rule tells you you CAN cast the spell... but a few words later, you're told you must still respect all conditions applying to casting a creature spell.

If I steal a hundred dollar from a loot of one thousand, people might notice;

If I steal a hundred dollar from a loot of one million, I might get away with it;

If I wish to steal even more and still go unnoticed, I need to make the loot bigger.

702.34a does specifically say that you may cast this card as a face-down 2/2 creature card, however, does that mean you could flip Zoetic Cavern face down in the graveyard and cast it from there?

No, it doesn't. There is nothing preventing you from doing that in the rules, but you don't normally have specific permission to cast spells from the graveyard either.

As such 702.34a is not specifically granting the ability to cast the spell, but rather it is indicating how you can cast it in an alternate way assuming you have some specific permission to cast it from wherever it is. (I will concede that perhaps 702.34a could be worded better) 

Oracle allows you to play lands from the top of your library, it does not allow you to cast spells from the top of your library and as such when you flip Cavern face down to cast it as a creature spell, you can not because you do not have permission to do so.

Note: Oracle is not giving specific permission either rather it's giving an alternate location where you can take the action described in 305.1

702.34a does specifically say that you may cast this card as a face-down 2/2 creature card, however, does that mean you could flip Zoetic Cavern face down in the graveyard and cast it from there?

Obviously not, however I suspect Pickman620 would argue that if you had Crucible of Worlds in play, then you could, due to his misconception that it is "still a land" somehow despite being flipped.

Maybe this will help resolve some confusion:
As 2Goth4U noted, the rule says "you may cast this card as a face-down 2/2 creature card."  That "as" is there for a reason. That sentence does NOT mean "You may cast this card, period.  It is a 2/2 creature card."  It means cast is "just as if it were" a 2/2 creature card, which means you have to obey ALL the rules on casting creature cards.

And again, this is all spelled out exaclty in the very next rule, 702.34b, where it expicitly says you use the effects and restrictions of a 2/2 creature, "and not the face-up card’s characteristics"  Like it or not, not being able to cast creature cards from your library IS a restriction, even though there is no specific rule saying "You can't cast creature cards from your library"
