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.
