Once during your turn (before your attack), you may count the number of Energy cards attached to the Defending Pokémon and attached to your Active Pokémon. If the Defending Pokémon has fewer Energy cards attached to it than your Active Pokémon does, you may attach 1 Energy card in your opponent's discard pile, if any, to the Defending Pokémon. You can't use this power if Tentacruel is affected by a Special Condition.
Flip a coin. If heads, the Defending Pokémon is now Poisoned.
