During your opponent's next turn, if this Pokémon has full HP and would be Knocked Out by damage from an attack, it is not Knocked Out, and its remaining HP becomes 10.
Flip 3 coins. If 1 of them is heads, this attack does 20 more damage. If 2 of them are heads, this attack does 60 more damage. If all of them are heads, this attack does 120 more damage.
