Pokémon Power Drive Off
As long as Light Arcanine is your Active Pokémon, once during your turn (before your attack), if your opponent has any Benched Pokémon, he or she chooses 1 of them and switches it with the Defending Pokémon. This power can't be used while Light Arcanine is Asleep, Confused, or Paralyzed.
If the Defending Pokémon is a Baby Pokémon, this attack does 10 damage instead of 50. If the Defending Pokémon is a Basic Pokémon, this attack does 30 damage instead of 50.
