Gondar, the Bounty Hunter

Shadow
Track—At the beginning of each upkeep, put a
bounty counter on target creature.
Whenever Gondar deals combat damage to a
player, destroy target creature he or she controls
that has a bounty counter on it. If it does, create
two treasure tokens and draw a card.
"I'm never going back to Revtel, Gondar. Try to force
me, and you're a dead man."
—Mireska, to Gondar.
