Poké-PowerJet Stream

Once during your turn (before your attack), if Blastoise is your Active Pokémon, you may flip a coin. If heads, discard an Energy card attached to Blastoise, if any. Then, if there are any Energy cards attached to the Defending Pokémon, choose 1 of them and discard it. This power can't be used if Blastoise is affected by a Special Condition.
