What I did here is I pretty much took the main VR, and shifted mons around based on my opinions. I put my thoughts next to everything I moved. Tiers are not ordered internally, just alphabetized.
S Rank:
S Rank
Cinderace
It's the second best thing in the meta, with only Magearna being better. Incredible speed tier, high power, and the coverage required to beat the entire metagame. It has some good checks in Slowbro, Pex, Lando, Heatran, Hippowdon, and Garchomp, that keep it from being busted (yet.)
Garchomp
Incredibly splashable pick that provides a ton to every team. A wide range of good sets, and some incredibly threatening tools that put it a cut above A+.
Landorus-Therian
Role compression god. It makes an appearance in nearly every game, and does everything you want it to well.
Magearna
Just gonna note here that Mag is still #1. It blitzes through everything with the right set. No true counters exist. Suspect worthy.
A Rank:
A+ Rank
Dragapult
No longer competing with Spectrier makes it the undisputed best Ghost in the tier. It is an excellent pivot and status spreader than can win games on the spot against teams lacking a way to beat it reliably, which is getting harder and harder to do. DD sets are an underrated HO tool.
Heatran
Rillaboom
Incredible offensive threat. It busts through walls with Wood Hammer, forces progress with Knock Off and U-turn, and revenge kills a ton of things with Glide. Grassy Terrain weakens the many Earthquakes of the tier. Rilla's traits are extremely desirable.
Slowbro
A bulky water to rival the Pex. FuturePort with Regen is excellent and creates excellent momentum and progress. It also checks 3/4 of the S tier mons.
Slowking-Galar
Incredible SpD wall and pivot, pretty much fits on any team. It lives for a long time and can target many top threats effectively. Super hard to switch into. A- is a criminally low placement.
Tornadus-Therian
This is the best hazard removal in the tier, as well as an excellent breaker with NP. It has a ton of longevity and also offensively checks all of the big 4. The 5th best mon in the tier imo.
Toxapex
A Rank
Blissey
It's still the best special wall in existence and it still gets massive momentum with Teleport. Blissey is excellent by virtue of holding a ton of teams together. It also is one of the best Mag switch-ins, even if Trick is annoying.
Clefable
While still excellent, it isn't anywhere near as splashable. Right now it's the worst it's been all generation.
Corviknight
It provides a great Lando and Chomp counter, and also is due for a rise with Spectrier gone.
Ferrothorn
Still a great mon, just not as valuable because of how exploitable it is for big threats like Cinderace. Spikes are incredible and underrated, though.
Hydreigon
While its defensive sets are basically gone, no longer being forced to run them actually help it in my opinion. NP is very threatening and can potentially take advantage of some of the best mons in the tier.
Melmetal
The big issue with Melm is its vulnerability to all of the big 4: Ace, Chomp, and Lando all threaten it with SE STAB, while Mag can do a ton of damage and get momentum with Volt Switch, KO a weakened one with Focus Blast or Aura Sphere, or cripple it with Trick. It also hates all the contact punishment in the tier right now. Still awesome, but not A+ levels of awesome.
Tapu Koko
As a Koko conoisseur, I can assure everyone that this placement is totally deserved. A fast pivot with an incredible STAB combo and quite a bit of longevity with Boots and Roost. It provides offensive counterplay to stuff like Ace and Torn as well.
Zapdos
A- Rank
Excadrill
The utility Drill brings to the table is undisputably great, but the gods that are Lando-T and Garchomp definitely cut into Excadrill's viability. Sand Rush sets and Rapid Spin are still both excellent as well and it deserves a spot near the top of A-.
Hippowdon
Being an excellent physical wall and good rocker that checks some big threats like Ace, Mag, Garchomp, Lando, and Heatran makes it better than before. Honestly, I could see it even go up to A.
Kartana
Kyurem
This thing scares me to death, holy heck. It has several excellent sets and kinda 6-0s Rain. Underrated and excellent breaker.
Mandibuzz
Spectrier (and Urshifu, to an extent) being gone does result in it being overall worse, especially with the utility other Defoggers provide, but Mandibuzz still certainly is a good Defogger.
Nidoking
Slowking
Tapu Fini
I think that Fini was placed a little too high in the first place, but it still is an important mon in the tier. Just not as good as it was when Urshifu was around.
Tapu Lele
B Rank:
B+ Rank
Aegislash
Excellent breaker that loves the recent bans, as both Urshifu and Spectrier deleted it. I think it ought to maybe even rise to A-, but it does lose to 3/4 of the big 4.
Dracozolt
Latios
Moltres
Still an ok Defogger and check to some big threats, it's just worse than before. I like Zapdos, Torn, and Corv much more as Defoggers but Moltres has its place.
Reuniclus
All the way up here? Oh yeah, it's because it's usable now with its biggest counters gone. Reuni does Reuni things, and is an excellent wincon and balance breaker.
Skarmory
Excellent wall, hazard setter, and Defogger. Spectrier leaving made it even better. Can counter Lando and Chomp quite well, which, as it happens, is crucial in this tier.
Swampert
Underrated role compression mon with rocks and pivoting that can prove valuable. I think that its niche is strong enough that it could potentially find itself in A- one day.
Tangrowth
Tyranitar
Tyranitar came away a little worse than before, no longer having the niche of being a Spectrier counter. However, I expect some offensive sets to be a little better as well, so maybe it'll rise back up. Defensive sets still can handle Dragapult, but it hates getting burned or paralyzed, and U-turn does a lot more than seems reasonable.
Zeraora
I might be jumping the gun here, but Zera is a great speed control and offensive pivot that outruns pretty much the entire metagame and makes great progress throughout the course of a game.
B Rank
Amoonguss
Blaziken
Crawdaunt
Dragonite
Gastrodon
Hawlucha
Kommo-o
Magnezone
Regieleki
Suicune
I think that it doesn't do its wincon job well enough to be in B+. Still a good pick, but not as good as it was ranked.
Urshifu-R
Urshifu-S leaving made it much more usable. No longer is it directly competing with public enemy number 1.
Victini
Volcarona
Zarude
B- Rank
Alakazam
Greatly underrated and extremely scary offensive threat imo. NP with Psyshock lets it bypass common SpD walls like Blissey and Glowking.
Barraskewda
Buzzwole
I think it's better than most people do as a wall, but obviously it was already dying out before Urshifu left and is worse than before. Still, it handles Lando and Chomp really well which is a niche that not many things in the tier have.
Ditto
Gengar
I think that Gengar is super scary to face. It just needed to not be beat by the two best mons in the tier. Now it can stretch its legs a little bit and use its wide range of sets to be a good offensive threat.
Kingdra
Moltres-Galar
Still a pretty ok wincon and HO mon, but B was altogether too high for something so limited.
Nidoqueen
Pelipper
Scizor
Tapu Bulu
Bulu is worse than Rilla, lacking several crucial tools, but it has better bulk, Synthesis, Horn Leech, Stone Edge, CC, and the Fairy typing to make up for it. Underrated threat, no doubt.
Zapdos-Galar
Still has to compete with Kanto Zapdos, but C+ was overkill. It can be quite scary to face. Worthy of B-.
C Rank:
C+ Rank
Azumarill
Bisharp
Urshifu leaving marginally increased its niche. It is super hard to switch into, but also hates all of the big 4.
Blacephalon
Spectrier leaving helps it. While still niche, it's got a bigger niche.
Celesteela
Hatterene
Why was it B- before? Idk but this thing can be pretty threatening, just not at the level for which it was initially ranked.
Jirachi
Keldeo
I think that C was a little harsh, so it's in C+ now. So there.
Latias
Mew
Ninetales-Alola
Obstagoon
Quagsire
Rotom-Heat
Rotom-Wash
Shuckle
Terrakion
Thundurus-Therian
Togekiss
Weavile
Urshifu leaving widened its niche a bit. It beats Lando and Chomp, and Ace hates getting Knocked.

No longer does it have a niche.
And that's it!
