I'll help with the one I've used.
Mega Swampert loves the rain thanks to swift swim. I assume you've already got one, but if not, try to get one with an Attack or Defense boosting nature (sacrificing Sp.Atk). Waterfall, Ice Punch, Earthquake, and Power-Up Punch works well. It's defenses are high enough to pull of the PUP once or twice against something to make it's other moves lethal. It'll need something to deal with Grass though, so have a decent Poison or Flying Pokemon to endure the hit on switch.
He works well with:
- Jolteon (100% accurate Thunder, it can even be used to set up Rain if you want),
- Toxicroak (If it has dry skin, it gets healing each turn. It also counters grass types for Swampert),
- Nidoking (again, deals with Grass types, but shares ground typing weaknesses. With Sheer Force and the special moves it can learn, this guy can turn into your special attacker. Ice Beam/Thunderbolt/Sludge Wave/Focus Blast with an Assault Vest?).
It's not impossible to do an all water team, but if you find something that counters you, you'll go down HARD. Kingler does much the same things Swampert does, just not as well.
Other Pokemon recommended to work well with Swampert include
- Crobat (Defog to clear hazards, switch into grass type attacks aimed at Swampert, while Swampert switches into Ice/Elec attacks aimed at Crobat. Acrobatics with no item is a real shocker as well. Toxicroak has less HP, but more types of moves it can learn)
- Electrode (Faster set up of Rain Dance, can also do Screen and Taunt. Fill the remining slots with Thunder, Volt Switch, or Explosion. This thing can not take hits though. Jolteon is more powerful.)
- Tentacruel (Special Wall, gets regen from rain with Rain Dish ability. With Leftovers/Black Sludge as well, it'll heal 24% of HP!)
Other Recommendations:
- Pokemon with Hurricane (Noivern)
- Pokemon with Hydration + Rest Combo and high defensive stat (Goodra for example)
- Pokemon with Defog/Rapid Spin.
- Pokemon resistant to Grass
- Pokemon weak to Elec/Fire.
- Pokemon with Rain Dance + High Speed.
- Pokemon with Light Screen + High Speed/High Def.
- Pokemon with Wish (and even Baton Pass and a boosting move) to heal Swampert (Umbreon)
- Pokemon with Entry Hazard such as Stealth Rock or Spikes (Chesnaut, Steelix, Aggron) (If you use Rapid Spin, it wipes only your opponents hazards. If you use Defog, it removes all hazards but also your opponents Light Screen/Reflect. A ghost type to "protect" your own hazards from your foes rapid spin wouldn't hurt)
- Another Pokemon to Mega Evolve in-case your up against something that screws Swampert or Rain Dance strategy (Gardevoir or Steelix)
Swampert, Gardevoir/Steelix, Toxicroak, Jolteon, Swellow, Haxorus seems good IMO. Swellow isn't the best flying type, but it can do well against weakened foes. Haxorus is just a beast no matter the team it's used on.
When in doubt, pick your faves, and play them to their (and their allies) strengths.

Hey, a guy won the last competition with pachirisu, so just use who you want!
Made me so damn happy. Then again the rest of his team was good, and Pachi was acting as a sponge. The highlight was seeing it SURVIVE the hits it pulled toward it.
