oh man, thats sweet... so basically tortured existence + krovikan horror does to a graveyard what survival + nabob does to a library. Pretty intense... I think I might just have to brainstorm with this card :P

A lot of it is dependant on Tortured Existence.  Along with Krovikan Horrorthat is the decks form of card advantage.  But basically you can use a sac outlet, in this case Carrion Feeder and Krovikan Horror, to permanently remove creatures and cards in hand with Mesmiric Fiend and Faceless Butcher by sacrificing them after their come into play effect resolves without passing priority.  Then the leave the battlefield trigger goes on top of the enter the battlefield trigger.  Buried Alive is a tutor of sorts, especially if Tortured Existence is out.  You usually get Mesmiric Fiend, and 2 Krovikan Horror for hand removal and Faceless Butcher and Horrors for creature removal.  You just have to be really careful to make sure you get creatures on top of the Horrors in your graveyard so you can keep returning them to your hand.  Corpse Dance is basically your win condition.  The fact that it is an instant and has buyback is pretty good.  You can Corpse Dance Terastadon at the end of your opponents turn destroying your own permanents or problematic ones on his side.  Corpse Dance exiles the creature at the next end step, so if you cast it during his end step the creature won't get exiled unitl your end step.  Doing that can result in 18 power coming at them on your turn.

hey chris, can you explain to me briefly how this deck works? I read through most of the cards, and there seems to be some neat tech going on, but I doubt I'm getting all of it :P
