Demonlord Belzenlok

Flying, trample
When Demonlord Belzenlok enters the
battlefield, exile all cards from the top of your
library until you exile a nonland card, you may
put that card onto the battlefield or 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.
