Once during your turn (before you attack), you may turn all basic Energy attached to all of your Pokémon into R Energy for the rest of the turn. This power can't be used if Charizard is affected by a Special Condition.
Flip 2 coins. If 1 of them is tails, discards 3 Energy cards attached to Charizard. If both of them are tails, discard all Energy cards attached to Charizard.
