Raikou

The rain clouds it carries let it fire thunderbolts at will. They say that it descended with lightning.

Pokemon Power — Lightning Burst: Whenever you attach a Lightning Energy card from your hand to Raikou, if your opponent has any Benched Pokémon, he or she chooses 1 of them and switches it with the Defending Pokémon. This power stops working while Raikou is Asleep, Confused, or Paralyzed.

Lightning Tackle (50): Flip a coin. If tails, Raikou does 20 damage to itself.
