Yanma.

Flip a coin. If heads, this attack does 10 damage to each of your opponent's Pokémon. Don't apply Weakness and Resistance. Then, if your opponent has any Benched Pokémon, he or she chooses 1 of them and switches it with the Defending Pokémon.

This attack's damage isn't affected by Weakness, Resistance, Pokémon Powers, or any other effects on the Defending Pokémon.
