Daring Stunt

Daring Stunt enters the battlefield with a Show counter if an opponent was dealt damage this turn.
At the beginning of your end step, if an opponent
was dealt damage this turn, you may sacrifice
Daring Stunt. If you do, draw a card for each Show counter on it. Otherwise, put a Show counter on it.
Whenever a creature deals combat damage to you, remove all Show counter from Daring Stunt, and
you lose 1 life for each show counter removed this
way.
