Demonlord Belzenlok

Flying, trample
When Demonlord Belzenlok enters the
battlefield, exile cards from the top of your
library until you exile a nonland card, then
put that card into your hand. If the card's
converted mana cost is 4 or greater, repeat
this process. Demonlord Belzenlok deals 1
damage to you for each card put into your
hand this way.
