Whenever your opponent plays a Trainer card from his or her hand during his or her next turn, your opponent flips a coin. If tails, that card has no effect. (Your opponent still discards that card.)
Once during your turn (before your attack), you may flip a coin. If heads, your opponent’s Active Pokémon is now Poisoned. If tails, your Active Pokémon is now Poisoned. This power can’t be used if Venomoth is affected by a Special Condition.
