Hi guys and girls ! I played UU enough to have an opinion about what is Broken in my opinion, what's really good and will stay for sure in the tier and what is usable and pretty good. I also listed all new mons with no interest in UU for the moment.
Remember it's MY opinion, please share your thoughts with me I would love to discuss all of them !
The clearly Quickbanworthy :
(Calm mind + Stored Power with Tera Fairy & Dazzling Gleam... With Sub or Protect as a fourth move... Please stop with this and let's quickban this in January)
The Suspect Worthy :
(This thing is the scariest pokemon if you don't have Blissey, because of how threatening he can be with Tera + Nasty Plot)
(The Tera Fire to make him ignore Ice Shard from Ice Pokemon such as Weavile or Cetitan, with Moxie or Intimidate, an awesome bulk, awesome movepool... Just OMG)
(An amazing typing, with first Impression, Bulk Up... It's one of the scariest mon in this tier)
(There is absolutely no joke, Scarf or Band + Tera Flying and it nukes all the defensives mons)
Very good :
(The combo of a potential good tera typing, recover, body press and rapid spin makes him an awesome defensive pick)
(Belly Drum + Aqua Jet and Tera Water is monstrous, but is that banworthy ? I don't think so for the moment.
(No comment on this, it's a perfect SpDef mon)
(With Suicide lead sets or Shell Smash sets, this thing can't be bad and will always destroy non-prepared teams)
(Hazards, Spin, Volt Switch, body press... This is a perfect Suicide lead)
(DD, good typing, good bulk, Moxie or Intimidate and an awesome Tera user...)
(I never saw him but Psychic Terrain + Unburden and SD seems really good)
(Hazards, Slack Off, awesome bulk and whirlwind)
(Nasty Plot, Hazards and good Tera abuser. The loss of Roost + Defog is annoying)
(Prankster + Screens, T-Wave, Spikes...)
(SD + E-speed and Tera Normal is insane)
(Scarf + Steel trap, Tera Blast to compensate the need of a move who hit Steel types)
(In a meta that offensive like that, it's a king)
(Awesome speed + Roost and Defog, the best Defog user. He resists to First Impression and CC from the Slither Wing and can RK him.)
(Better than Gastrodon because of Unaware, but Tera Grass and Espathra/Gengar explodes him)
(Awesome versus a lot of mons, like Azumarill. Volt turn + WoW or Trick for the coverage, but no Defog or Pain Split anymore)
(The combinaison of Electric/Ground types with an awesome speed and SpAtk makes him a really good pokemon right now with Scarf or Specs)
(The reason why Alomomola is not here. Wish Pass, Encore, potential Tera user...)
(Ice Shard, Ice Spinner, SD, good speed, Tera user...)
(Remember when he was scary ? Now think of it with EVIOLITE)
EDIT :
(I forget the twins, but obviously Slowking with Chilly Reception instead of Teleport still have an amazing pivot move. Scald no here anymore is annoying but not as much as for Slowbro.
Good Pokemon:
(The loss of Scald and Knock Off are important, but it's still a really good Wish passer)
(Intimidate, WoW, Morning Sun, E-Speed... Arcanine can't be "bad")
(Usable in rain only. The loss of Flip Turn and the fact he didn't get Wave Crash make him struggles)
(Hazard setter, with Body Press and Trick Room)
(With Hail, Belly Drum & Ice Shard, this thing is pretty scary)
(Typing & Bulk + Sheer Force + Hazards)
(Hazards + Spin + Ice Shard)
(Adaptability + Tera can possibly save him)
(In rain, with Swift Swim and Shell Smash...)
(Scrappy + Good typing make him really decent)
(Yes, again, but Rain + Wave Crash, Ice Spinner and Aqua jet is the best option for rain teams)
(New toy syndrom with the new ability, it will not be in the tier imo but it's still is a threat for the moment if you're not prepared)
(Too much of raw power in this tier for him to be "very good" but still an awesome pick)
(Awesome bulk, movepool and stats, so maybe with a Tera it can be good. Assault Vest, Band, Specs, Scarf... It's a world of imagination)
(Magic Bounce, CM + Stored Power and Draining Kiss. Suffer from the comparaison with Espathra)
(Not as good as Salamence because of his speed, not the best user of Band First Impression... That's not a bad mon but he suffers)
(He Suffers from comparaison with Slither Wing but still have Guts to be different)
(Not bad for Terrain Combos in HO)
(Not incredible but not bad, maybe in rain teams)
(The typing is awful, Tera for him is maybe not the best idea, but his stats + Booster Energy can make him threatening)
(Hazards + Intimidate, It's not as good as he always have been, but still)
(Good speed, Accelerock, Hazards...)
(His talent with Hazards make him a potential good pick against some Physical pokemon)
(Rain setter, Roost, U-Turn)
(Good with Shell Smash, but not as much as Espathra)
&
(Good mons,
is a bit better but it depends on what you need as typing)
(Screens user, but you don't want to put screens on him... Prankster + Recover/WoW/Taunt/Encore is obviously a good thing)
(Offensive, Defensive + WishPass...)
(It's gimmick but can surprise)
(Water immunity, can counter rain, SD + CC Sucker Punch or Nasty Plot + Vacuum Wave...)
(Specs with Tera + Boomburst)
(Same as Sylveon, but only defensive)
(Same)
(A better Brute Bonnet ?)
EDIT :
(I forget about him !! No Scald, no Teleport, a nerf of Slack Off... He can't even be played with Assault Vest, so I'm guessing in some teams, Slowbro could be better with the Lefties than Slowking... Maybe also a possibility in Trick Room teams...)
The "Niche" pokemon :
(One of the rare decent defoggers in the tier, but this is Altaria...)
(A good movepool, the typing a bit problematic and the only stats problem with him is his speed)
(Rapid Spin, immunity to Hurricane...)
(Like Dhelmise, having three STABs is good, he have a nice typing, but that's all)
(It's gonna be a hot take, but he have the same speed as Cacturne, the same typing, 12 BS more in Atk. The only good thing is his bulk and... x4 weakness to U-Turn makes him just suffers. Wo-Chien seems better defensively)
(Fake Out, Bullet Punch, Close Combat and Headlong Rush, Knock Off, Elementary Punches... His movepool is insane and Guts with Flame Orb or Assault vest makes him really decent...)
(The typing and speed saved him)
(HJK/CC + Scarf/Band, Pure Power and Tera Fighting ?)
(I'm forced, because of Revival Blessing, to put him as a "Niche mon"... But it's just because of a broken move)
(Same as Pawmot...)
(Clearly not that good but his typing and his moveset makes him better than the other bad mons of the gen)
(He's good in Sun, but without Torkoal, it's just a niche pokemon)
(In this meta, sticky is not bad)
(Honestly good versions of Tauros, but why using this instead of another mon ?)
(We can't forget Quiver Dance + Tera)
New mons with no real interest :
Arboliva (He have a decent bulk, an awesome SpAtk, but he's slow with a bad typing and movepool, you don't want to invest Tera in him)
Bellibolt (He's not really usefull, he don't have any coverage, have an average ability...)
Dachsbun (He's immune to fire and he's a Wish passer... but Alomomola is better at this and there is no Fire mon that good to put him in a team instead of the other Wish passers)
Dudunsparce (Just hope for haxx, that's the classic "Use it if you're lucky")
Farigiraf (He have a bad typing, he's slow, it's hard to do something with him)
Grafaiai (I tried this in the first OU days to counter Flutter Mane, it was a FAIL. I thought about him to counter Gengar, it's another FAIL)
Klawf (I'm sad about this but... Not good enough...)
Mabosstiff (A better Mightyena, that's all)
Oinkologne (Next)
Squawkabilly (Good talents, but the stats are awful)
Tatsugiri (Awesome typing but like Kingdra, he lacks of usefulness)
Toedscruel (The typing is so bad, and the fact he hit last is bad... He would love, unlike Amoonguss, to hit Spore fastly)
Veluza (Bruxish is better)
Wugtrio (Don't use this... If you want to make him good, put a Ground Tera and rename this Dugt... Wait... Oh no just use Dugtrio)
Sorry once again for all the grammar mistakes !!
is a nice pivot/stallbreaker I find.
can be threatening in Rain against slow teams.
is a very useful switch-in to Weavile/Bisharp/Gyarados/Lycanroc. 
can have a lot of success with Scarf set, still OHKOs Pawmot/Weavile
