Found a convoluted Infinite combo, needs 4 cards to get off: Solemn Simulacrum , Ashnod's Altar , Nim Deathmantle , Pawn of Ulamog .

Sac Solemn Simulacrum to Ashnod's Altar , gaining 2 colourless mana floating. Stack Pawn of Ulamog and Nim Deathmantle s triggers so that Pawn of Ulamog s will resolve first. Sac the Eldrazi Spawn created by Pawn of Ulamog s trigger to Ashnod's Altar BEFORE Nim Deathmantle s trigger resolves to have 4 colourless floating mana. Then resolve Nim Deathmantle , paying the 4 mana cost to have Solemn Simulacrum return to the battlefield, triggering card draw when it dies, and a tapped swamp when it returns. Rinse and Repeat :D

Was too hasty with my post of the combo, their are other cards that work in place of the cards in the combo, but Ashnod's Altar and Nim Deathmantle have to be there.

Another card that will work jus as well replacing Pawn of Ulamog is Ogre Slumlord , also producing tokens to sac to Ashnod's Altar .

Some other cards that will also work with the aforementioned combo, replacing Solemn Simulacrum :

• Abyssal Gatekeeper , Butcher of Malakir , Bone Shredder : Sweep all other players creatures off the board, with Butcher of Malakir being the best.

• Noxious Toad , Ashen-Skin Zubera , Mesmeric Fiend : Remove all cards from all other player's hands, with Mesmeric Fiend being the best. Sac it before it's second ability resolves, and the cards shall be forever exiled.

• Blood Artist . Win. Make all opponents lose all their life. The best one for the combo.

• Not quite as good, but still do SOMETHING with the combo: Myr Retriever , Junk Diver , Cadaver Imp , Big Game Hunter , Pilgrim's Eye .

Also, if you have Harvester of Souls on the field, it's even happier days. Or Grave Pact .

If I ever get to Diabolic Revelation for 4, I know what I'll be grabbing :D
