Salamence

Once during your turn (before your attack), you may reveal the top card of your deck. If that card is a basic Energy card, attach it to 1 of your Pokémon. If that card isn't a basic Energy card, discard it. This power can't be used if Salamence is affected by a Special Condition.

Does 20 damage to 1 of your opponent's Benched Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)
