Flip a coin. If heads, the Defending Pokémon can't attack. (Benching or evolving the Defending Pokémon ends this effect.)

Flip a coin. If heads, this attack does 10 damage to each of your opponent's Benched Pokémon; if tails, this attack does 10 damage to each of your own Benched Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)
