Emrakul, the Promised End rewards a graveyard containing different card types. Each type among cards in your graveyard reduces the thirteen-mana cost by one, allowing a deck with lands, creatures, artifacts, enchantments, and spells in the graveyard to cast it well ahead of the printed total. A single card can contribute more than one type.
The cast trigger lets you control a targeted opponent during their next turn, after which they receive an extra turn. That gives you access to their decisions and resources for one turn, potentially disrupting their board or using interaction against another threat. The extra turn afterward is part of the same arrangement, so plan for what that opponent will still have when control returns to them.
Self-mill and varied card types support the cost reduction naturally. Artifact creatures and enchantment creatures help cover multiple types, while fetch lands can place lands in the graveyard. Reanimation skips the cast trigger, so a deck seeking the turn-control effect wants to cast Emrakul rather than merely put it onto the battlefield.
The creature itself provides flying, trample, and protection from instants. That protection does not stop every sweeper or permanent-based answer, and it does not make the spell impossible to counter while on the stack. Treat the body and cast trigger as complementary payoffs. A carefully prepared graveyard lowers the cost, and a thoughtful controlled turn can improve the board enough for the large evasive creature to finish the job.
