If your opponent has any Benched Pokémon, choose up to 2 of them. This attack does 10 damage to each of them. (Don't apply Weakness and Resistance for Benched Pokémon.)

Flip 3 coins. This attack does 20 damage times the number of heads. If you get at least 1 heads, the Defending Pokémon is now Poisoned.
