A set I run is
Azumarill @ Sitrus Berry
Ability: Huge Power
EVs: 252 HP / 252 Atk / 4 Def
Adamant Nature
- Aqua Jet
- Play Rough
- Return
- Belly Drum
I use a scarfed dragon that comes in after Azumarill's counters are taken out. Uses Outrage. Then, they're forced to bring in another scarfer to outspeed and use Ice Beam or a Dragon move. Then, Azumarill gets a free switch and can use Belly Drum as the opponent switches out. After that, just Aqua Jet to victory.
