Politoed

Frog Song

Whenever Politoed's attack damages the Defending Pokémon (after applying Weakness and Resistance), if there are more than 3 Poliwags, Poliwhirls, Poliwraths, and/or Politoeds in play (including your opponent's), that attack does 40 more damage (no matter how many heads you get). This power stops working while Politoed is Asleep, Confused, or Paralyzed.
