The Gambler

If you would lose the game, flip this card face up.
The player who delivered the killing blow may
choose Dead or Alive.
•If the player chooses Dead, destroy all
creatures on the battlefield and you lose the game.
•If the player chooses Alive, they draw 5 cards
and untap 3 lands they control. Your life total
becomes 1, damage is removed from the stack,
and until the end of your next turn you
cannot lose the game.
