Attach this card to 1 of your Pokémon that has Bruno in its name. That Pokémon may use this card's attack instead of its own. At the end of your turn, discard Bruno's Technical Machine 01.
Before doing damage, choose 1 of your opponent's Benched Pokémon and switch it with the Defending Pokémon. Do the damage to the new Defending Pokémon. This attack can't be used if your opponent has no Benched Pokémon.
