Dragonite UR -> Somewhere in C (HP, Def, SpD, Spe)
Dragonite faces heavy competition from Salamence, however what makes it different is the fact that it has Multiscale, which can enable it as a very efficient bulky setup option, usually with Dragon Dance/Roost/Dual Wingbeat/Earthquake or Heal Bell. It can really steal games against teams that rely on pivot + fast breaker as you can get out of control fairly quickly.
Magnezone B- -> B+ (HP, Spe)
Magnezone's ability to trap steel is very underrated. It can help some team styles thrive once Corvi/Skarm/Ferro are gone. HP is also a legit option on it. With 100 HP and above, Magnezone can directly switch in against Bisharp and beat it 1v1. With Grassy Surge support in speed slot, it can even beat Excadrill 1v1 with a free switch and go for Iron Defense immediately.
+2 252 Atk Life Orb Bisharp Knock Off (97.5 BP) vs. 4 HP / 252 Def Magnezone (100 HP): 286-339 (83.6 - 99.1%)
252 Atk Excadrill Earthquake vs. +2 4 HP / 252 Def Magnezone in Grassy Terrain: 124-148 (43.9 - 52.4%)
Regieleki UR -> C- (SpA, Atk, Def, SpD)
As an attacker, it's very strong but deadweight if there's any ground (Although Ancient Power can deal a bit against Lando-T). It's still an option for HO with its dual screens though, and you can fit it in whatever slot is left.
Rillaboom B- -> B (SpDef)
Rillaboom on the SpDef slot is surprisingly durable, and it's also a good fit on more offensive build with its terrain control, Knock Off and U-Turn.
Scizor C -> C+/B- (HP, SpDef)
Scizor with a good HP is a very solid pivot option. It should be noted that it's better used as an utility mon rather than straight up sweeper, it can help in a lot of matchups, between Defog, Knock Off and being a revenge killer.
Tapu Fini A -> A-
Fini struggles a lot right now. Even though it's a good Crawdaunt check, the lack of recovery makes it really hard to stay healthy throughout a match in a meta where games go longer than before.
Tapu Lele (Def)
I see Lele used in Def more often than SpA and Spe. For once, it already has great SpA, and it's usually used to protect another friendly mon in Speed slot since there's more options for Spe slot than SpA with >=130 Speed mons being mostly Koko and Zeraora, who can't really break immediately and Koko overrides the terrain.
Weavile A- -> B+
Weavile just isn't a reliable enough option, and I hardly ever see it for good reasons. It can't break steel birds as well as Crawdaunt, and its normally coveted speed is lower than 130.
Blaziken UR -> C (Spe)
Blaziken usually has a big 4mss due to its middling speed. Without Protect, it's outpaced by all Scarfers while running it means forgoing a valuable coverage. With an option to gain a better Speed, it can now set up more comfortably. It's still walled by some mons depending on what coverage you run, and you have to give up on the speed slot, which is a big opportunity cost.
Latias UR -> B- (Def)
With a good defense stat and your opponent has no Dark type, this can steal the game with Stored Power/ Calm Mind/ Refresh/ Roost
Jirachi UR -> C+/B- (Spe, Atk)
As much as I hate this, it can be a very real wincon as you flinch your opponent into oblivion.
Nihilego UR -> Somewhere in C (Def)
Nihilego is quite fat, can be a Rocker and TSpiker in one slot, while also provides Knock Off. It's walled by pretty much everything though, so yeah.
Salamence UR -> A-/B+ (Def)
Defensive Salamence has worked out so well for me, between the mixed moveset to handle what it needs like Flamethrower for Kartana and Buzzwole, Dragon Tail to deny further setup. Good Def + Intimidate allows it to handle dangerous threats like Crawdaunt and Conkeldurr. A physical wall with reliable recovery truly makes it different than Lando-T.
Skarmory (HP)
I've seen more HP Skarm than SpDef, it works way better. HP should be its main option
Tapu Bulu B -> B-
Tapu Bulu just can't compete in this Spe slot anymore. Its lack of options Rillaboom has is not enough to justify the ability to beat Ho-Oh. To make matters worse, it is also forced out by the omnipresent Eternatus, and it will still get walled every game depends on what you decide to run.
UR -> C- (Spe)
Thunderbolt, Focus Blast, Sludge Wave covers almost everything except Eternatus and Lando-T, with a NP it's very hard to stop. Being an offensive check and Volt Switch deterrent against Rotom, Zeraora and Koko is also very welcomed.
Venusaur (Def)
Def is very useful on Venusaur to help it more easily set up. With Groudon's defense, Venusaur can comfortably set up against stuffs it normally can't.
Bronzong UR -> C- (HP)
Bronzong is a niche option on TR teams. It provides role compression in Trick Room, Rock and Explosion, however most of the time you will want Cresselia over it.
Darmanitan UR -> C+ (Spe)
In case you think your Victini doesn't provide enough nuke, you can run Darmanitan to completely send all defense cores to the underground. Running one with Scarf and the other with Band also alleviates some pressure as Darm isn't always forced out after attacking, at the cost of nuking itself alongside its foes.
Gardevoir UR -> C/C- (Spe, Def)
Being able to use weather against foes can be valuable sometimes. It also helps against other good abilities such as Sheer Force, Adapt, Intimidate and immunity abilities.
Milotic UR -> C- (Def)
It has to compete against Slow twins, but it carves a niche in its Haze to stop setup, and does better against Crawdaunt.
Polteageist UR -> C+ (Spe, Def, HP)
It can outpace a lot more threats with a better speed while still dealing good damage, however its limited movepool prevents it from being higher.
Porygon2 (Def)
I don't think there's much to say about this
Registeel UR -> C/C- (HP)
Let's just say you won't enjoy playing against my demon Registeel set. I also saw Atk Registeel on ladder, however that's a gimmick at best.
Reuniclus (SpD)
RegenVest Reuniclus
Stakataka UR -> C+ (HP, Spe)
Besides a solid Trick Room user, it can run Heavy Slam in speed slot instead and quite good at keeping Rock up due to Heat Crash.
Suicune UR -> C (SpA, Spe)
With fewer Water immunities, Crocune might just make its stage once again
Togekiss UR -> B-/C+ (Spe)
Same as Jirachi
Weezing-Galar UR -> C- (HP)
Being able to stop most abilities it their track, especially Regenerator punishes recovery less sets, and with Pain Split and Toxic/Will-O-Wisp, it can be a real pain.
Xurkitree UR -> B- (Spe)
Ideally, you run this alongside Koko and fires off nuke, you actually have coverage against Ground and Dragon unlike Eleki so it might just steal the game.
Barbaracle UR -> C+ (Atk, Spe)
It has some options to consider, such as Grass Knot, Cross Chop and Earthquake, all of which are useful against particular threats
Bewear UR -> B- (Def, Spe)
I saw Bewear in arkeis stall team. Its only problem is Victini, besides that though it gets to abuse 120/230 Def Body Press which is quite neat. I don't know if Spe is actually viable for it, but it might be so I just list it.
Cresselia UR -> C+/B- (SpA)
Cresselia doesn't actually need more bulk, it however can get better SpA to reduce the number of Calm Mind it needs to deal decent damage. Against some teams this can literally 6-0 from team preview.
Indeedee UR -> C (SpA)
It nukes quite hard, but low speed and being helpless against most matchups is sad.
Regidrago UR -> Somewhere in C (SpA, Spe, Atk)
Regieleki but walled by Fairy instead, at least you can explode.
Sigilyph UR -> C- (SpA, Spe)
I tried hard to make this work, but it surprisingly still misses out on a lot of 2HKO even with Tinted Lens and Eternatus's SpA. It's also somewhat reliant on good prediction even with Tinted Lens. Without Spe it can still outpace a lot of mons in Spe slot, but it's still slow otherwise.
Slurpuff UR -> B- (Atk)
Slurpuff has a place on HO teams thanks to its unique ability to imposter proof itself, which is very threatening to HO otherwise. With a better Atk, it can actually KO things at +6 now.
Araquanid (HP)
HP Araquanid can be quite obscene and bulky enough to set Web multiple times if needed
Exploud UR -> C+ (SpA)
Boomburst can decimate a lot of unprepared teams, and it has enough coverage for all Steel and Rock mons. Sadly it's outspeed by just about anything not being a wall except Trick Room
Guzzlord UR -> B/B+ (SpD, Def)
This mon is just insanely fat. It can even tank Dragapult's Draco, however without it Guzzlord can just endlessly wall pretty much anything without a Fairy move. Between Dragon Tail, Sludge Bomb and Knock Off, it has a lot of utilities as well.
:sirfetch Sirfetch'd UR -> C- (Spe)
I'm not a fan of coinflip every turn, but this has caused me a lot of troubles when it keeps critting.
Tauros UR -> C+ (SpA)
Tauros is like Nidoking/Nidoqueen without good STAB, but it's a lot faster. Nidoking sits in a sad speed tier, just below most legends' speed so it often finds it hard to actually claim kills, Tauros usually relies on 2HKOs, but it can actually go mixed with Body Slam to target some mons like SpD Gastrodon.
Tyrantrum UR -> B+/A- (Spe)
Banded Head Smash slaps. HARD. If you pay attention you might see this can come in and
miss claim lives until it runs out of PP. You will be disappointed by the misses though, so sometimes you might click other moves.
Xatu UR -> C- (Def, HP, SpD)
Xatu is still not very bulky even after inheriting, so you should NEVER use it in anything except Stall. It pretty much stops all hazard setters from getting hazards while having a reliable recovery, which Espeon and Hatterene lack. Espeon has to resort to low PP Morning Sun or Wish while Hatterene even has to use Life Dew.
Drampa UR -> C+ (Spe)
The ability to threaten all weather abusers can save the day. Fire Blast smacks Excadrill, Arctozolt, Chlorophyll and Slush Rush users. Energy Ball punches a hole in Seismitoad, Tyranitar, Arctozolt. Thunderbolt destroys Pelipper and Draco kills Kingdra. Sash and Scarf can both alleviate the matchup against non weather in some ways, although I prefer Scarf.
Kingdra A- -> A (SpA)
Welcome back, Kingdra. Rip Mantine
Raichu-Alola UR -> B+/A- (SpA)
The best abuser of Electric Terrain. The downside is you have to run Pincurchin or Koko not in SpA slot.
Sceptile UR -> C- (Atk)
Way worse typing than Hawlucha both offensively and defensively, however given the right conditions it can still put in some work.
Aggron UR -> C (Atk)
I saw this in a TR team, it does pack some punch. You really only want to use this in the Atk slot in TR though, otherwise Tyrantrum is better.
Claydol UR -> C+/B- (HP)
Gotta say, I run this in my Hail team and packing both Spin and Rock in addition to having Teleport to pivot into the weather abusers is amazing.
Glastrier UR -> B+/A- (Spe)
Indeed a controversial opinion. However I find it hard to believe this mon is bad when it has good coverage and tons of bulk. What always held it back was low Speed + bad defensive typing forcing it out, I have seen this a lot and it always puts in work. Even if not B+/A- it should be ranked.
Ninjask UR -> C+ (HP)
The fastest Final Gambit user. Even if your opponent knows what this does it can just U-Turn out.
Whimsicott UR -> C+ (SpA, HP)
My Grass spam team enjoys Whimsicott's unique perk of Prankster + Nature Power. It even has Encore and U-Turn for utility!
Abomasnow Idk
I only put this here cause I saw beauts put this mon to work, I still wouldn't rate it but will just leave it here
Accelgor UR -> C- (HP)
Another Final Gambit users but with Spikes for HO
Arctovish UR -> C- (Atk, Spe)
You only use this if you want both Arctozolt and Arctovish in a hail team. Together they can wear down their shared checks to allow the other to sweep.
Eldegoss UR -> C- (Any)
I saw arkeis use this in his stall team as a spinner, it's decent to say the least
Ludicolo UR -> A-/A (SpA)
Don't be fooled by its carefree look, it's a deadly rain sweeper. Most common rain answers are bulky Water (Washtom, Gastro, Vaporeon) which all get nuked by its second STAB, and it has Ice Beam to deal with Dragon and Grass as well.
Persian UR -> B- (Atk)
Ok ok hear me out. Know how Pikachu was the best revenge killer? Silk Scarf Persian with Fake Out and Feint is a budget Pikachu (And with a stronger Fake Out actually). With the same Attack, Pikachu hits 240 BP with FakeSpeed + Light Ball while Persian hits 189 BP with Silk Scarf + Technician and STAB Fake Out + Feint. Its higher Speed can prove to be useful when it U-Turns out.
Pincurchin UR -> C (HP)
A small price to pay to use Raichu-A
Pyukumuku B -> B+ (Def, SpD)
Pyukumuku can do something else besides being an Unaware wall. And that's Innards Out combined with Def/SpD from Pheromosa to nuke whatever you want. It can force constant mind games that your opponent is at a disadvantage.
Sableye UR -> C+ (HP)
If your opponent doesn't have PsySurge, this mon can be extremely annoying to take down
Shuckle B- -> B (HP)
Shuckle can run Contrary Shell Smash to some extent with a stall set, but I find Shuckle HO to work pretty well these days.
Swoobat UR -> C+ (HP)
The added bulk can help it steal games, but more often than not it's still not enough to save it.
Vikavolt UR -> B- (Spe)
Getting a decent speed to set web is a godsend (literally). Vikavolt also threatens some Defoggers, making it quite unique in its role.
Wigglytuff UR -> C- (SpD, Def)
Dragapult's ban makes its stonk plummet, but it can still WishPort, although its bad ability compared to Clef usually means it loses too much HP in the process.
Mareanie UR -> C- (SpD)
Basically only usable in stall to handle rain.
