Whenever a creature an opponent controls dies, exile it with a hit counter on it. Assassins, Mercenaries, and Rogues you control have deathtouch (Any amount of damage this deals to a creature is enough to destroy it.) and "Whenever this creature deals combat damage to a player, you may remove a hit counter from a card that player owns in exile. If you do, draw a card and create two Treasure tokens (A Treasure is an artifact with ", Sacrifice this artifact: Add one mana of any color.")."
