Ildrik, Grand Inquisitor

Lifelink, Deathtouch
When Ildrik enters the battlefield, Fateseal 5, then look at the bottom five cards of target opponent's library. Choose one of those cards and exile it face down. For as long as that card remains exiled you may look at it and you may spend mana as though it were mana of any color to cast it. (To Fate seal 5, Look at the top five cards of target opponents library. Put any number of cards back on top or bottom of their library in any order.)
