Todays card of the day from Daily MTG is a very good Eldrazi that (unfortunately) got overshadowed by it's legendary bretheren:
I have to confess that I forgot all about this card and it's just begging for a deck to be built around it. And the first step in doing so is to take advantage of something that this card can do and Emrakul, Ulamog, and Kozilek can't do... it can be reanimated.
With Faithless Looting soon to be released in Dark Ascension, it seems obvious to me that a Red/Black deck would fit best. Off the top of my head, excellent cards to include would be things like Chainer's Edict, Wildfire, and Liliana of the Veil. Liliana in particular was made for this deck. She could force a creature to be sacrificed, she could help discard an It That Betrays to the graveyard, and it can force a mass sacrifice effect.
Toss in a few copies of Squee, Goblin Nabob to take advantage of both Faithless Looting and Liliana of the Veil and you have yourself a deck!
