Answer 1

Gen VII (PvE/PvP)
Politoed (M) @ Mystic Water / Waterium Z / Life Orb
Ability: Drizzle
EVs: 4 HP / 252 SpA / 252 SpD or 4 Def / 252 SpA / 252 SpD
Modest Nature
- Hypnosis
- Surf / Hydro Pump
- Ice Beam
- Mud Bomb

Hypnosis - Puts target to sleep and can set up pretty much anything you have in your arsenal.
Surf/Hydro Pump - Use for STAB and to deal with Fire, Rock, and Ground types. Surf also makes him a great candidate, not only for single battles, but for double battles, too. Surf can heal the right partner while damaging the opposition. It is also a better accuracy choice over the single target Hydro Pump. Hydro Pump is also decent with more power at the expense of less accuracy. It is also good for single battles.
Ice Beam - This is for coverage. It will help fend off Dragon, Grass, Ground, and Flying types.
Mud Bomb - I chose this move over Earthquake for the obvious reason. POLITOAD'S NATURE! Yes, with lower power and lower accuracy, Mud Bomb doesn't seem feasible, but with Politoad's SAtk stat at its max, Mud Bomb's power comes to par, maybe even exceeding Earthquake's power. I haven't done the math, yet. You'll lose a little accuracy as a cost, but the coverage move is worth taking down Fire, Electric (weakness), Poison, Rock, and Steel types.

Answer 2

Politoed @ Damp Rock
Ability: Drizzle
EVs: 232 HP / 56 Def / 220 SpD
Calm Nature
- Mind Reader
- Hypnosis
- Whirlpool
- Haze

Use Politoed as a lead for a rain dance team. Use mind reader to hit guaranteed hypnosis or whirlpool. Use haze if your opponent starts to stack up on stats. Politoed is by far my favorite Pokemon and I think this moveset works really well.

Answer 3

SubDrum Politoed set
Gen 8 ZU

Politoed @ Salac Berry
Ability: Water Absorb
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature
- Substitute
- Belly Drum
- Liquidation
- Ice Punch

Should be self-explanatory. Substitute is to help Politoed setup Belly Drum. If you can, use Belly Drum after the Substitute has been setup, knocking Politoed's HP to 25%, activating Salac Berry. Liquidation is STAB. Ice Punch is for grass types.

Answer 4

No one's posted a doubles moveset for Politoed yet? Wow.

Doubles UU

Politoed @ Damp Rock
Ability: Drizzle
EVs: 248 HP / 8 SpA / 252 SpD
Careful Nature
IVs: 0 Atk
- Muddy Water / Scald
- Helping Hand
- Protect
- Icy Wind

Muddy Water is STAB and causes spread damage, but it's accuracy is shaky. If you aren't ok with Muddy Water's accuracy use Scald instead. Helping Hand powers up your ally's next attack. Protect is to keep Politoed safe for a turn. Icy Wind is for speed control. The Damp Rock increases the duration of Politoed's rain.
