Reshiram & Zekrom 

Discard up to 3 in any combination of basic Fire and basic Lightning Energy cards from your Benched Pokémon. This attack does 90 damage for each card you discarded in this way.

This attack does 170 damage to 1 of your opponent's Benched Pokémon. If you played N's Resolve from your hand during this turn, this attack also does 170 damage to 1 of your opponent's other Benched Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) (You can't use more than 1 GX attack in a game.)
