I suppose I should showcase some STABmons Doubles sets.
Weezing-Galar @ Sitrus Berry
Ability: Neutralizing Gas
EVs: 252 HP / 16 Def / 112 SpA / 84 SpD / 44 Spe
IVs: 0 Atk
- Sludge Bomb
- Moonblast/ Dazzling Gleam
- Baneful Bunker
Already a good Pokemon in regular DOU, Galarian Weezing is in my opinion much more annoying in STABmons Doubles with it having Moonlight to recover, allowing it to stay in the field longer. Additionally, Baneful Bunker compresses as a protection move and spreading poison. After using Baneful Bunker for a bit, I do miss Toxic Spikes since it's better at spread poison rather than waiting someone to hit it with Fake Out or V-create, but Galarian Weezing needs Moonlight so what can I do. Same spread as the standard one, you could replace Moonblast with Dazzling Gleam in case of redirection.
Bouffalant @ Sitrus Berry
Ability: Sap Sipper
EVs: 252 HP / 252 Atk / 4 SpD
- Extreme Speed
- High Horsepower/ Megahorn
- Whirlwind/ Fake Out/ Feint/ Recover
Through finding a good Extreme Speed user, I stumbled across Bouffalant who has good bulk and Sap Sipper to block Sleep Powder and Grassy Glide. Anyway for its moves, Extreme Speed serves as a powerful priority attack that allows it to go first regardless of what speed control the opponent has, High Horsepower acts as a powerful coverage move and Megahorn to dish heavy damage to Rillaboom and Indeedee. Whirlwind to phaze setup attackers such as Kommo-o or Trick Room setter out. Alternatively, Bouffalant could go for Fake Out to give its ally some momentum to work with, and Feint for breaking protection.
As for no Earthquake, you don't really use Earthquake unless you gain STAB from it since spread move deals x0.75 damage unless it targets one Pokemon. Even then, Rillaboom is everywhere.
Drapion @ Choice Band
EVs: 252 Atk / 4 SpD / 252 Spe
- Wicked Blow
- Gunk Shot/ Poison Jab
- Stomping Tantrum/ Sucker Punch
- Parting Shot/ U-turn
Finally, I want to try out Wicked Blow and Drapion happens to be a good answer with its Sniper ability boosting the power of critical hits. Stomping Tantrum in case of Incineroar, Parting Shot, and U-turn enables Drapion to switch out depending on what you want, either to lower offensive power or dealing some chip damage.
