Maybe it's just me, but doesn't perilous vault have a negative interaction with both chained to the rocks and banishing light? I get the need for a sweeper, but I feel like you sideboard perilous vault completely for the first match, and side out both those cards for the solid sweeper if your opponent has enchantment hate.
Windmill slam that Whelming Wave. Card is good enough on it's own; the fact that there is only one other blue card in the pack strongly signals your opponents to not go into blue.
While Deepwater Hypnotist isn't something to sneeze at, I wouldn't expect it to be a 3 or 4 pick, and I would definitely not expect someone to go into blue solely based off of this card.
I'm going with Dimir first, although I am going to play each of the guilds. Dimir has the best limited bomb; M12 showed us that mill is just devastating in limited. However, I think that gruul has the best chance of taking the win though because their overall pool is just so aggressive and good.
I think sever the bloodline could be pretty good constructed side board tech for the new standard, what with there being now like 4 or so clones running around.
EDIT: Also, with all the graveyard shenanigans, could we see some sort of ravenous trap variant or something at common?
I think the flavor is that she is walking in the woods and finds a random body on the ground, not the last thing that died. That being said, alright card. Not great, but not terrible.
I would say maybe cut a couple angels and add a couple swords. The angel tops out your curve, and if you're going aggro, do you really want 4 of them in your deck when the game wants to be over a by turn 7-8?
They could just have the werewolf subtype on the flip end of the card. That way, spells that reference that type can't hit Garruk unless he's specifically flipped.
