Once during your turn (before your attack), choose 1 of your Active Pokémon or 1 of your Benched Pokémon and switch Gardevoir with that Pokémon. This can't be used if Gardevoir is affected by a Special Condition.
Choose 1 Pokémon (yours and your opponent's) with the fewest remaining HP (excluding Gardevoir) and that Pokémon is now Knocked Out.
Put this card onto your Active Gardevoir. Gardevoir Lv. X can use any attack, Poké-Power, or Poké-Body from its previous Level.
