Ok, really great team and I love using whacky pokemon myself!
I would add Pincurchin, boosts bellibolts electric type moves, activates iron hands quark drive to deal more damage. (I would replace him for talonflame)
note: you might wanna change iron hands EV's depending if you want bulk or defense.
Pincurchin @ Terrain Extender
Ability: Electric Surge
Tera Type: Flying
EVs: 252 HP / 4 Atk / 252 Def
Iv's 0 Sp
Relaxed Nature
- Zing Zap
- Protect
- Sucker Punch
- Recover
zing zap has good flinch chance cause of trick room, sucker punch is insurance if trick room fails, protect and recover you just can't give up.
for flutter mane I would put iron bundle because you want to disable other flutter manes this guy is perfect, he is 1 base point faster than flutter mane (wooo!)
Iron Bundle @ Focus Sash
Ability: Quark Drive
Tera Type: Ice
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Ice Beam
- Freeze-Dry
- Protect
- Hydro Pump
just a really great mon :)
now since you got 2 water types and any electric type move on an electric terrain will kill Gyarados I would recommend another intimidate user, specifically Landorus Therain, Immune to electric so basically telepathy meaning it would work great with bellibolt! (I am pretty sure he is allowed in this format please correct me if I am wrong)
Landorus-Therian @ Yache Berry
Ability: Intimidate
Tera Type: Rock
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Protect
- Taunt
- Rock Slide
- Brick Break
so yache berry is so opponents can't force you to tera and there are a few people who have ice coverage and unnerve so he should be safe. If he is not allowed I would recommend krookodile, maybe he is better?
so I think you got a pretty good team and I love to see people who use not popular pokemon. I wish you success with your team!
(If you are thinking of changing them for more bulky pokemon you could just put electric seed)
