Azumarill

Azumarill is an incredibly diverse Pokemon that can run a wide range of sets with varying coverage moves that allow it to fit onto multiple team styles with ease. Azumarill's near-exclusive access to Huge Power turns its pitiful base 50 Attack into one of the highest Attack stats in the metagame, especially when used alongside a Choice Band or Belly Drum. This allows Azumarill to function as a potent sweeper or wallbreaker, especially with its great STAB coverage in Water / Fairy, which hits the majority of the metagame for neutral or super effective damage, including top-tier threats such as Colossoil, Tomohawk, and Landorus-T. Additionally, Azumarill's access to priority in Aqua Jet and great coverage moves in Knock Off, Superpower, and Bulldoze help it excel in offensive roles ranging from wallbreaker to revenge killer. Azumarill also has a great defensive typing in Water / Fairy, with important resistances to common attacking types such as Fire, Water, and Dark. This typing in combination with Azumarill's above-average 100 / 80 / 80 bulk helps it switch into and check threats. Unfortunately, a horrible base 50 Speed stat leaves Azumarill outsped by the majority of the metagame, including common walls such as Pyroak, Clefable, and Skarmory, which do not invest heavily in Speed. This low Speed and reliance on Aqua Jet cause it to be easily revenge killed by common Electric-, Grass-, and Poison-type Pokemon, notably Mollux and Plasmanta.
