Bronzong G

Once during your turn (before your attack), you may move an Energy card attached to 1 of your Pokémon SP to another of your Pokémon. Then, put 2 damage counters on Bronzong G. This power can't be used if Bronzong G is affected by a Special Condition.

Does 10 damage to each of your opponent's Benched Pokémon that has any damage counters on it. (Don't apply Weakness and Resistance for Benched Pokémon.)
