Once during your turn (before your attack), if you have a Stadium card in play, you may use this power. Each Active Pokémon (both yours and your opponent's) (excluding Pokémon SP) is now Poisoned. This power can't be used if Skuntank G is affected by a Special Condition.
If the Defending Pokémon tries to attack during your opponent's next turn, your opponent flips a coin. If tails, that attack does nothing.
