Qi'ra, Crimson Manipulator

Whenever a creature an opponent controls dies, exile it with a hit counter on it.
Assassins, Mercenaries, and Rogues you control have deathtouch 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.”

It's not that kind of game, Han. The object isn't to win. It's just to stay in it as long as you can. -Qu'ira
