Empoleon

Sporting one of the best defensive typings in the game, you'd be forgiven for thinking that Empoleon is generally seen as a defensive threat. However, its typing, stats, and movepool actually provide it the perfect pairing of tools to become a menacing offensive threat. With Drizzle support, its unique SubPetaya set can sweep any unprepared team, and when building a rain offense team, Empoleon should always be considered.
