You can use this attack only if you go second, and only during your first turn. Shuffle 1 of your opponent's Benched Pokémon and all attached cards into their deck.
Flip a coin. If heads, your opponent's Active Pokémon is now Paralyzed and Poisoned.If your opponent's Active Pokémon is Poisoned, this attack does 100 more damage.
If a Stadium is in play, this attack also does 30 damage to each of your opponent's Benched Pokémon, and discard that Stadium. (Don't apply Weakness and Resistance for Benched Pokémon.)
If this Pokémon has any Darkness Energy attached, it gets +100 HP, and the attacks it uses do 100 more damage to your opponent's Active Pokémon (before applying Weakness and Resistance).
