Once during your turn (before your attack), when you attach a Grass or Psychic Energy card from your hand to Vileplume (excluding effects of attacks or Poké-Powers), you may use this power. If you attach a Grass Energy card, the Defending Pokémon is now Asleep. If you attach a Psychic Energy card, the Defending Pokémon is now Poisoned. This power can't be used if Vileplume is affected by a Special Condition.
