Ampharosデンリュウ

Poké-PowerEnergy Connect

As often as you like during your turn (before your attack), you may take a basic Energy card attached to 1 of your Benched Pokémon and attach it to your Active Pokémon. This power can't be used if Ampharos is affected by a Special Condition.

You may discard all Lightning Energy cards attached to Ampharos. If you do, this attack's base damage is 80 instead of 40.
