The Eleventh Brother

Haste, Trample, Menece, Deathtouch

Whenever a creature an opponent controls enters the battlefield, if it was cast from their hand, exile that creature. Until this creature leaves the battlefield, you may cast cards exiled this way, without paying their mana cost.

Whenever you cast a creature from exile, mill the top five cards of your library. If you have no cards in your library, you win the game.
