As often as you like during your turn (before your attack), you may move a Water Energy attached to 1 of your Benched Pokémon to your Active Pokémon. This power can't be used if Blastoise is affected by a Special Condition.
Return 2 Water Energy attached to Blastoise to your hand. Choose 1 of your opponent's Pokémon. This attack does 100 damage to that Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.)
