Flip 3 coins. If exactly 1 is heads, this attack does 40 damage. If exactly 2 are heads, remove 3 damage counters from the Defending Pokémon. If the Defending Pokémon has fewer damage counters than that, remove all of them. If all 3 are heads, this attack does 60 damage. If all 3 are tails, remove all damage counters from the Defending Pokémon.
