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 mana value is 4 or greater,
repeat this process. Demonlord Belzenlok deals
1 damage to you for each card put into your hand
this way.
