Dreamgorge Baku

Skulk
Whenever Dreamgorge Baku deals combat
damage to a player, put a +1/+1 counter on Dreamgorge Baku, then exile the bottom card of
their library face down. You may look at it for as
long as it remains exiled.
When Dreamgorge Baku dies, you may cast one
of the cards exiled with it without paying its
mana cost.
