Pyke, The Bloodharbor Ripper

Flash, Deathtouch, Skulk, Ward {2}
The List - Whenever a creature deals combat
damage to you, put a list counter on it
Death From Below - {1}: Pyke deals damage equal
to his power to target creature with a list counter.
At the beginning of each end step, if there are no creatures with list counters, return Pyke to it's
owner's hand
When a creature with a list counter on it dies,
create a treasure token
"My list just keeps getting longer"
