Charizardリザードン

Poké-PowerBurning Energy

Once during your turn (before your attack), you may turn all basic Energy attached to all of your Pokémon into Fire 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, discard 2 Energy cards attached to Charizard. If both are tails, discard all Energy cards attached to Charizard.
