Poliwrath

While often overlooked due to its fellow amphibian—Politoed—acquiring Drizzle as a Dream World ability, Poliwrath is valid Pokemon in VGC in its own right. Sporting two water-related abilities in Swift Swim and Water Absorb, it can function well on a rain team. Poliwrath's unique Water / Fighting typing and respectable movepool allow it to perform both offensive and supportive roles on a team. While its stats may be considered a bit too balanced at times, its exclusive access to having both Belly Drum and Swift Swim should not be overlooked. If you're looking for a risky strategy or a solid support Pokemon, give Poliwrath a try.
