At the beginning of your end step, you may put
a bounty counter on target creature or
planeswalker you don't control.
Whenever a creature or planeswalker with a
bounty counter on it dies, choose one —
• You gain 3 life.
• Samus Aran, Bounty Hunter deals 2 damage
to any target.
• Draw a card, then discard a card.
