What about Dark Ritual as a backup for Simian Spirit Guide ? In case you don't get that second Guide, you have a chance at having Dark Ritual as a backup to cast Goryo's Vengeance .

good call. what to take out for it though? the Bloodghast ?

Yeah that'd be my first choice. Even if you do manage to get him in the grave with Griselbear then make your land drop, reanimate him, and play Vengeance, he's not going to make a difference.

Changed it up. Thoughts?

Post board, Bloodthrone Vampire is a better sac outlet because you can Pod Deathrite into it as well as draw it, whereas you can only draw the Viscera Seer .

o man the deck is so unconditional but soooooo awesome

migitcrawlar it's actually pretty consistent. Turn one wins are luck draws, but consistent turn two wins happen all the time. Changed it up a bit since its original intro

I made a quick version of this deck that i might try running, because it can mostly board into perfect storm game two with leaving thoughtseizes in for a slower game and also pacts of negation http://tappedout.net/mtg-decks/a-demons-fury/
