Octilleryオクタン

Choose 1 of your opponent's Pokémon. This attack does 30 damage to that Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) Switch Octillery with 1 of your Benched Pokémon.

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