Kingdra δ

Poké-PowerDragon Curse

Once during your turn (before your attack), if Kingdra is your Active Pokémon, you may put 2 damage counters on 1 of your opponent's Pokémon with δ on its card. This power can't be used if Kingdra is affected by a Special Condition.

If the Defending Pokémon is Pokémon-ex, this attack does 30 damage plus 30 more damage.
