By targeting Cephalid Aristocrat with the zero-cost ability of Warrior en-Kor, you create an endlessly repeatable loop without ever needing to tap a land or spend a resource. Each time the en-Kor redirects its imaginary damage, the Aristocrat’s reflexive trigger forces you to mill two cards. This self-contained engine lets you effortlessly dump your entire library into your graveyard, setting up massive reanimation or graveyard-based win conditions with absolute ease.
