Assault Vest Azumarill, a staple of this Generation. Need a Greninja counter? Check. Need a ZardX check? Check. Need a Fairy to beat Thundy 1v1? Check (not advisable tho). Azumarill is one of this generation's best, with one of the best typings in the tier. Capable of stoping Scarfed Garchomp, which is a HUGE threat to my MManectric.

Waterfall: Reliable STAB, more oftenly used when I can assure a 2HKO with it, meaning Play Rough misses wont be necessary. It deals respectable damage, and nothing much to say.

Aqua Jet: Priority. Allows me to beat Thundy 1v1, Lando 1v1, and just revenge kill many mons in general, such as the ever-so-rare Mamoswine. Also, it forces other Priority mons that are weak to use their Priority moves, rather than a potential Super Effective move on me (Sash Loom).

Play Rough: lol, this thing reks OU "switch-ins", so only MVenu and Ferro are safe. Beats ScarfRage/BandRage from the likes of Garchomp and Dragonite. Also, my strongest STAB move. Azu beats the likes of AV Conk, as Play ROugh OHKOs.

Knock Off: Since Ferro gets shat on by Gliscor, MManectric, and Talonflame, I didn't see the need to run Superpower. Knock Off allows me to punish common switch-ins like Ferro, knocking off Lefties or Helmets, easing up OHKO's/Recoil, respectively. It also allows me to heavily wear down stall, especially the like of Chansey, who can admittedly wall my whole team alone, bar Gliscor.

Just another Standard Azu :]
