Pyke, Bloodharbor Ripper

Deathtouch, Shroud
When Pyke the Bloodharbor Ripper enters the battlefield or dies, put a list counter on an
opponent's creature. At the start of your upkeep
if a creature has a list token, you may return
Pyke from the graveyard to the battlefield, it gains
haste until the end of turn. If Pyke kills a target
with a list token, create one treasure token.
"I've killed a lot of monsters, none of
them lived in the sea."
