All right, next, the sections on Attacking, Blocking, and Combat Damage--these will be in three separate posts. Questions? Comments? Suggestions for more questions?

Attacking[indent]
Q: I want to tap a creature to keep it from attacking--when do I have to do that?A: If you want a creature to be unable to attack, you have to tap it before your opponent gets the chance to declare it as an attacker--after that, it's too late.
The last chance to tap a creature to keep it from attacking is during the Beginning of Combat step, before the Declare Attackers step begins. (Note that at that point you technically don't know for
sure whether your opponent is going to attack with that creature or not...though you may be able to make a fairly accurate guess if he has a massive creature on the board and you have no blockers.)
If your opponent is rushing things and goes ahead without allowing you a chance to do the things you want, you are perfectly justified in getting him to back up so you can play the things you want to--Magic is not supposed to be a game of reflexes. If you had your chance and wasted it, however, there's no turning back.
--------------------------------------------------------------------------------
Q: Does untapping an attacking creature make it stop attacking?A: Not unless the spell or ability that taps or untaps it specifically says so. Once a creature is attacking, tapping or untapping it can't change that.
--------------------------------------------------------------------------------
Q: So what can make a creature stop attacking?A: A creature is removed from combat when something specifically says it removes it from combat (
Gustcloak Savior
), or when it leaves play (
Terminate
), changes controllers (
Grab the Reins
), stops being a creature (very rare), or is
regenerated. (Note that using something that regenerates a creature simply creates a shield that will perform the actual regeneration later, and doesn't remove the creature from combat right away; see the
Regeneration FAQ entry.) Nothing else (including tapping or untapping) will remove a creature from combat.
--------------------------------------------------------------------------------
Q: My opponent attacks with a particular creature--can I then do something before he attacks with his other creatures?A: No. All attackers are declared at once--there is never a time "between" two creatures attacking during the same combat phase.
--------------------------------------------------------------------------------
Q: My opponent's creature "attack[s] if able" for some reason, and there is some restriction on how or when that creature can attack. (For example, it's an Ember Beast
or I have a Ghostly Prison
in play.) What happens?A: When the time comes for your opponent to declare attackers, your opponent's creature is forced to attack if it is possible for your opponent,
at that very moment, to make it do so somehow. Your opponent is required to pay costs, declare other attackers, and so on, in order make the attack legal.
However, it's
very important to note that while the above is true, nothing is forcing your opponent to take unrelated actions that would then, in turn, make it possible for the requirements to be met so that that creature to attack.
To give an example, take the case of the forced-to-attack creature being an
Ember Beast
. If your opponent controls other creatures that are able to attack when it becomes time to declare attackers, he will be forced to attack with his Ember Beast and one of his other creatures, because Ember Beast must attack if able and it can't do so alone. It's possible
at that moment for your opponent to attack with the Beast and another creature, so he must do so. However, imagine your opponent's only creature in play is the Ember Beast, but he has a
Raging Goblin
in his hand. Playing the Goblin before combat would later allow his Ember Beast to attack (along with the Goblin), but your opponent is not required to do so, because that's a separate, unrelated action. Sure, it would allow him to fill the requirement later on, but the game isn't looking that far ahead--it only cares about what he can do
right as attackers are declared, and can only force him to do things right then and there. He isn't required to do anything before that if he doesn't want to.
For another example, take the case of you having a
Ghostly Prison
in play. While your opponent would be required to pay the two mana to let his creature attack if he had the mana
in his mana pool right at that moment, if he doesn't
already have the mana in his mana pool, he is not required to produce it if he does not wish to do so.[/indent][/indent]

Blocking[indent]
Q: Can a creature be blocked by more than one creature?A: A creature can
be blocked by any number of creatures. It can
block only one creature. (Unless specified otherwise.)
--------------------------------------------------------------------------------
Q: I want to tap a creature to keep it from blocking--when do I have to do that?A: If you want a creature to be unable to block, you have to tap it before your opponent gets the chance to declare it as a blocker--after that, it's too late.
The last chance to tap a creature to keep it from blocking is during the Declare Attackers step, just before the Declare Blockers step begins. (Note that at that point you technically don't know for
sure whether your opponent is going to block with that creature or not...though you may be able to make a fairly accurate guess if you're attacking with a massive creature that will kill him if he doesn't block.)
If your opponent is rushing things and goes ahead without allowing you a chance to do the things you want, you are perfectly justified in getting him to back up so you can play the things you want to--Magic is not supposed to be a game of reflexes. If you had your chance and wasted it, however, there's no turning back.
--------------------------------------------------------------------------------
Q: Does tapping a blocking creature make it stop blocking? Does it make it not deal combat damage?A: Not unless the spell or ability that taps or untaps it specifically says so. Once a creature is blocking, tapping it can't change that, and will have no effect on whether or not the blocking creature deals combat damage.
--------------------------------------------------------------------------------
Q: So what can remove a creature from combat?A: A creature is removed from combat when something specifically says it removes it from combat (
Gustcloak Savior
), or when it leaves play (
Terminate
), changes controllers (
Grab the Reins
), stops being a creature (very rare), or is
regenerated. (Note that using something that regenerates a creature simply creates a shield that will perform the actual regeneration later, and doesn't remove the creature from combat right away; see the
Regeneration FAQ entry.) Nothing else (including tapping or untapping) will remove a creature from combat.
--------------------------------------------------------------------------------
Q: If all the creatures blocking a particular creature are somehow removed from combat, does that make the creature unblocked?A: No. Once a creature becomes blocked, it
stays blocked for the rest of combat, no matter what happens to the creatures blocking it.
--------------------------------------------------------------------------------
Q: My opponent blocks my creature with another creature--can I then give my creature flying, fear, unblockability, or some other evasion ability to make it so the creature's no longer blocking?A: No. Once blockers have been declared, that's it. It doesn't matter whether the creature has some sort of ability that would prevent it from being blocked if you went through declaring blockers again--it's blocked
now, and that's all that matters.
--------------------------------------------------------------------------------
Q: My opponent blocks with a particular creature--can I then do something before he blocks with his other creatures?A: No. All blockers are declared at once--there is never a time "between" two creatures blocking during the same combat phase.
--------------------------------------------------------------------------------
Q: My opponent's creature "block[s] if able" for some reason, and there is some restriction on how or when that creature can block. (For example, it's an Ember Beast
or it's enchanted by Cowed by Wisdom
.) What happens?A: When the time comes for your opponent to declare blockers, your opponent's creature is forced to block if it is possible for your opponent,
at that very moment, to make it do so somehow. Your opponent is required to pay costs, declare other blockers, and so on, in order make the block legal.
However, it's
very important to note that while the above is true, nothing is forcing your opponent to take unrelated actions that would then, in turn, make it possible for the requirements to be met so that that creature could block.
To give an example, take the case of the forced-to-block creature being an
Ember Beast
. If your opponent controls other creatures that are able to block when it becomes time to declare blockers, he will be forced to block with his Ember Beast and one of his other creatures, because Ember Beast must block if able and it can't do so alone. It's possible
at that moment for your opponent to block with the Beast and another creature, so he must do so. However, imagine your opponent's only creature in play is the Ember Beast, but he has a
Mobilization
in play. Playing the Mobilization's ability before he needs to declare blockers would later allow his Ember Beast to block (along with the Soldier token), but your opponent is not required to do so, because that's a separate, unrelated action. Sure, it would allow him to fill the requirement later on, but the game isn't looking that far ahead--it only cares about what he can do
right as attackers are declared, and can only force him to do things right then and there. He isn't required to do anything before that if he doesn't want to.
For another example, take the case of the creature being enchanted by
Cowed by Wisdom
. While your opponent would be required to pay the two mana to let his creature block if he had the mana
in his mana pool right at that moment, if he doesn't
already have the mana in his mana pool, he is not required to produce it if he does not wish to do so.[/indent][/indent]

Combat Damage[indent]
Q: Does untapping an attacking creature or tapping a blocking creature prevent it from dealing combat damage?A: No.
--------------------------------------------------------------------------------
Q: If all the creatures blocking a particular creature are somehow removed, will that creature deal damage to the defending player?A: No. Once a creature becomes blocked, it
stays blocked for the rest of combat, no matter what happens to the creatures blocking it, and blocked creatures can't deal combat damage to the defending player. (Unless, of course, they have
Trample or a similar ability.)
--------------------------------------------------------------------------------
Q: When is my last chance to boost/shrink creatures to make them deal more/less damage in combat?A: If you want to change the size of a creature so that it deals more or less damage, you have to do it before that creature's combat damage is assigned at the beginning of the combat damage step. Once a creature assigns damage, that damage is dealt as originally assigned, no matter whether or not the creature has changed in the interim.
In most cases, that means you have to pump/shrink the creature during the Declare Blockers step. (If
first or
double strikers are involved in combat, you can wait until the first strike combat damage step to pump/shrink non-first-strikers.)
--------------------------------------------------------------------------------
Q: Can I sacrifice my creature (say, as a cost to play a spell or ability) and still have it deal combat damage?A: Usually, yes. If you play your spell or ability after combat damage has been assigned, but before it is dealt, your creature will already have assigned combat damage, and that damage will be dealt as assigned even if your creature disappears in the interim.
--------------------------------------------------------------------------------
Q: Can my creature be dealt more damage than its toughness?A: Yes. Things that deal damage to creatures don't "pull their punches" based on the toughness of the creature. If your creature is blocked by an 8-power creature, it's going to take 8 damage, no matter what its toughness is.
--------------------------------------------------------------------------------
Q: My creature is blocking or blocked by more than one creature. What happens?A: Your creature assigns damage equal to its power divided as you choose among all the creatures blocking or blocked by it. (Your creature will deal the same amount of damage it would if it was only blocking/blocked by one creature--you can just split it up between the the blocking/blocked creatures however you like.)
(Remember that creatures can normally only block one attacking creature each. There would have to be
something
special
in order for a blocking creature to be able to block more than one attacker.)[/indent][/indent]
