Zaybada, Mindcrawler

Flash Deathtouch
Emerge {2}{u}{b}{r}
Whenever Zaybada, Mindcrawler attacks exile the
top three cards of your opponents library. You
may look at these cards at any time, and may cast creature spells exiled this way, spending mana as
though it were mana of any color.
"Screams and moans and fetid smells follow Zeybada wherever he travels, his hosts unable to stop him as he burrows through their brain as agonizingly slow as possible"
