Ultimecia, Time Sorceress // Ultimecia, Omnipotent

Legendary Creature — Human Warlock

Whenever Ultimecia enters or attacks, surveil 2. (Look at the top two cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.) At the beginning of your end step, you may pay and exile eight cards from your graveyard. If you do, transform Ultimecia.
