Baalenoth, Abyssal Terror

Flying, trample, menace
At the beginning of your upkeep, look at the top
three cards of your library, put one into your
hand, one into your graveyard, and one into exile.
Whenever Baalenoth attacks, put a card exiled
with it into your graveyard and then Baalenoth
deals damage equal to the converted mana cost of
the exiled card to any target.
