once you have 6 mana zombie infestation on the battlefield and in your hand you have 1 treasure hunt 1 selective memory: play selective memory exiling every nonland card except your eldrazi creatures then play treasure hunt to reveal cards from the top of your library till you reveal a nonland card. hopefully you pull 8-10 cards that you can discard to zombie infestation for 2 2 zombies. your discards may include eldrazi so that you can reshuffle your graveyard back into library. If all else fails, you can either swing in with Inkmoths or you will cast an eldrazi eventually!
