AbilityRuler's Roar

Once during your turn, when you play this Pokémon from your hand onto your Bench, you may use this Ability. Look at the top 4 cards of your deck and attach a Basic Energy card you find there to this Pokémon. Shuffle the other cards and put them on the bottom of your deck.

This attack does 50 damage for each Fire Energy and each Lightning Energy attached to all of your Pokémon.
