Energy Reaction

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.

Disturbing Pollen

Flip a coin. If heads, your opponent can't play any Trainer, Supporter, or Stadium cards from his or her hand during your opponent's next turn.

Its petals are the largest in the world. As it walks, it scatters extremely allergenic pollen.
