The two Basilisk Collar where added to make sure you keep the feel empty and gain health. Also the imps to bring a must needed creature back eldrazi, specter..etc.

the other two eldrazi cant be in the graveyard. and they are 12-15 cost unless you have Nirkana Revenant or Hellcarver Demon its not gonna happen. Now Artisan of Kozilek is 9 and lets say you pull the mana to bring him out and you have another eldrazi in the graveyard? Looks dangerous. But I added Emrakul, the Aeons Torn just incase u want to discard him just to reshuffle your graveyard back yo your deck
I think you could cut down on 1 or 2 sphinx and add Lighthouse Chronologist or some more instants or counters, but low cost creature heavy has its advantage.
thanks, going to update it.
