@Astarael
Grind is a nice trick to connect what is, to what could be.
@cats_and_me
This is all of the right kinds of weird. The best kind of puzzles are the subtle kind, and there's plenty of times this would bite you in the ass, but just as many as it might not.
@Tequilasaurus
Obmutescer? Sure, why not. Odd seeing a Dimir card that is so good in combat.
@Matt_Holck
As stressed by myself and several others, this doesn't work. Morph and transform are mutually exclusive.
Morph requires a card to have a face and a back.
A double-face card is just that; a card with two face. They don't have a back and can't ever be face down.
@Purplebackpack
Nice effect, and a body that compliments cipher. Not bad.
@Tevish_Szat
I had to double check to make sure this wasn't riffing on Undercity Plague 
. I kind of wish it had... <_<
Neat effect.
@ColonialDragons
Sorry I didn't see this sooner, but I don't know what to do with this. "Leaves the battlefield" has no meaning in this sense. Does it become sacrificed? Bounced? Without knowing, I can't grade this.
@Rush
Don't change a thing.
@Tekkahedron
This has weird tension I don't particularly like; It has an ability that wants to be used pre-combat, and one that wants to be dealt during combat.
@Libe
It's hard for me to gauge this. On one hand, it's repeatable removal. On the other, it's slow and hard to do repeatedly. The effect itself is fine, I'm just not sure about the cost.
@Altimis
If Rapid Hybridization 
is fine, so is this. A fine card.
@Dudibus
*A* That's so cool. I love it.
@POSValkir
I'm not entirely kosher with another old keyword being reused, but I never said you couldn't, so whatevs. You can't target individual cards in your hand.
As the design is, ninjutsu fits in find with what the Dimir are up to.
@ConfusedAsUsual
I think the way this works is that which card is which when you blinkmorph is ambiguous. If so, I love it.
@FrankyFourFingers
A bit sledgehammery, but fine. It seems odd for blue-black to harm itself in such a way, but I suppose you wouldn't include a card with a drawback like that without some way to abuse it.
@Dream_Spinner
Interesting. I've always liked Torpor Orb 
kind of effects, so this appeals to me in particular.
@EyeballFrog
Something like that yeah. You'd have to have separate clauses for cards in your hand and on the battlefield.
As is, this is fine.
A good way to cheat things into play, or late game, make better use of any lands you draw.
@pablo
Doesn't work. ):
Tokens aren't cards, and thus, don't have cardfaces.
