Octillery

Poke-BODY: Suction Cups

As long as Octillery is your Active Pokémon, whenever the Defending Pokémon retreats, discard all Energy cards attached to the Defending Pokémon when it goes to the Bench.

If the Defending Pokémon tries to attack during your opponent's next turn, your opponent flips a coin. If tails, that attack does nothing.
