Absol ex

When Pokémon-ex has been Knocked Out, your opponent takes 2 Prize cards.

Once during your turn, when you put Absol ex from your hand onto your Bench, you may move 3 damage counters from 1 of your opponent's Pokémon to another of his or her Pokémon.

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.)
