Legendary Creature — Eldrazi

Emrakul, the Promised End costs {1} less to cast for each card type among cards in your graveyard.
When you cast Emrakul, you gain control of target opponent during that player's next turn. After that turn, that player takes an extra turn.
Flying, trample, protection from instants

An enigma as vexing as life itself.
