Lightning Cube 01
Attach this card to 1 of your Lightning Pokémon in play. That Pokémon may use this card's attack instead of its own. At the end of your turn, discard Lightning Cube 01.
Discard all Lightning Energy cards attached to this Pokémon. Then, flip a number of coins equal to the number of Energy cards discarded that way. This attack does 40 damage times the number of heads.
