Lots of mana production with this deck, also heartless summonings and eye of ugin to make the eldrazi cheaper. Quicksilver amulet is very useful in getting them out faster. Possible to have the big hitters out by turn 5 or have them steadily coming into play turn after turn with the overgrown battlement and elvish aberrations' mana production ther toughness is ok for the heartless summoning. I added innistrad garruk for creature searching, trample and some protection, as well as a doubling chant for getting more eldrazi out there.
