As often as you like during your turn (before your attack), if Elekid is anywhere under Electivire, you may move a Lightning Energy attached to your Pokémon to Electivire. This power can't be used if Electivire is affected by a Special Condition.

Giga Impact60

You may discard all Lightning Energy attached to Electivire. If you do, this attack's base damage is 120 instead of 60.
