Salamence DR 10

Once during your turn (before your attack), if Salamence is your Active Pokémon, you may switch 1 of your opponent's Benched Pokémon with 1 of the Defending Pokémon. Your opponent chooses the Defending Pokémon to switch. This power can't be used if Salamence is affected by a Special Condition.

Flip a coin. If heads, prevent all effects of an attack, including damage, done to Salamence during your opponent's next turn.
