You and your opponent play Rock-Paper-Scissors until someone wins. If you win, during your opponent's next turn, prevent all damage from and effects of attacks done to this Pokémon.
This attack does 10 damage to each of your opponent's Pokémon. Your opponent's Active Pokémon is now Confused. (Don't apply Weakness and Resistance for Benched Pokémon.)
During your opponent's next turn, if this Pokémon is damaged by an attack (even if it is Knocked Out), put damage counters on the Attacking Pokémon equal to the damage done to this Pokémon.
