Hi, I have decided to make a VR based on my somewhat limited experience with this tier, this isn't supposed to be super comprehensive but rather all the mons that I have seen be really consistent and benefit a lot from the rules of this format. Some of them are speculation since I haven't seen them firsthand so I might be underrating a few mons here, but overall I would say this is mostly accurate and reflects well what I've noticed to be the most useful and strong:
S
S-
A+ 
A

A-

B+ 
B






Other guys that don't benefit a lot from the format but are probably good just based on who they are and how they match up against the rest of the meta:
So, now with that laid out, before I move on to explaining some of the mons in this VR and their potential, I will preface it saying I'm number 2 on the ladder right now, and while that is a very good rank I don't feel like I have that much experience with the tier; this ladder is very slow and it's a bit hard to find matches, let alone matches with experienced players, which I find to be a huge shame because I like this tier way more than a good chunk of the permanent OMs, so this will hopefully spark a bit of motivation for people to try and experiment in this tier since I think there's huge potential and it's very fun. The meta is very decentralized with the exception of a few mons which make a lot of the matches feel a bit all over the place and hard to try to figure out what's good and what's not, which can be a good thing since a lot of pokemon get to shine, but also can make it harder for people getting into the tier and not knowing where to start and for experienced players to not really see it as a legitimate serious format. So I decided to make this personal VR as a way to have an outline for stuff that at least I think are good and are underexplored even.
Explanations:
Hisuian Goodra: This is the clear winner of this format as it often tends to do in other OMs, recovery on Shore Up and Strength Sap, an strong attacking move in Gigaton Hammer which hits hard even without investment, a lot of hazard setting options, and just the overall insane bulk of this mon makes it clearly the best mon of this tier, for now at least. Its presence lowkey invalidates a lot of special attacking mons and it is by far the best answer to boomburst primarina which is another top tier, disrupts setup with Dragon Tail and racks up damage with the hazards, Knocks Off items left and right and just sits there being a big bitch. Best mon in my eyes for sure
Primarina: Boomburst liquid voice, yep, that's it, that's the mon. The calcs on this thing are really stupid, most mons hit by it neutrally will just die, its presence makes balance teams pretty hard to use if they aren't relying on goodra, since in most cases even resists are taking over half, best way to deal with it is pressuring it offensively and pivoting around with your fat mons, but prim can really break through almost everything. The set I use and find to be the best is Boomburst, Calm Mind, Psystrike and Burning Bulwark. This thing getting Psystrike is half the reason it's so hard to counter, because if you want to wall it with your Toxapex, Blissey or Clodsire you have to be prepared for it to take 80+% or just be KO'd when prim is at +1. If hgoodra ever gets banned I think you will have to take this thing with it. This is not some unbeatable mon, just very strong and very oppressive.
Ok shorter sections for the next ones
Toxapex: I think it's slightly overrated but people value it a lot, teleport is just a huge game changer for it and single handedly makes it one of the safest mons to use, topsy turvy also being a very popular choice to stop setup mons. Mortal Spin, Trick Room, Mirror Coat, Thunder Wave, a lot of good options for it, solid
Ting Lu: it's Ting Lu but it can teleport, literally what else could you ask. Gets a lot of good options, trick room support, topsy turvy to stop setup, tidy up to clean hazards and even potentially sweeping on its own, I've seen a couple offensive Ting Lus and they are scary. Very good mon.
Greninja: hot take, I think fast stab fleur cannon is stupid. Protean gren is a menace in this format, either specs or scarf it just gets a lot of good options and coverage with F, very good
Cinderace: haven't experienced it first hand but I've been told this mon is insane and I get why, it just has a LOT of options and all of them can beat different teams, with SD on top of that this is just a really unpredictable mon.
Skeledirge: in my opinion the premier physical wall, just typing, bulk and the new access to strength sap plus potential pivoting option with chilly reception gives it a lot of utility.
Sand: basically the reason I'm #2 on the ladder, with heat and damp rock being banned it makes sand the defacto best weather in this tier, and these two abuse the format a lot as well. Tyranitar gets a lot with Tidy Up, Precipe Blades, Parting Shot, it's a huge utility mon that can also fill it's old dragon dance role with Tidy Up but with better utility. Excadrill is just another example that fast encore is broken in gen 9, the almost perfect coverage with Diamond Storm makes it really hard to deal with, plus the constant speed boost of sand rush, it gets dragon ascent too if you find yourself struggling with grass types. Just a really good archetype with these two leading it
Won't go over every single one but here's a few things I would like to highlight
Trick Room is really strong in this format, the fact every T mon gets the combination of trick room + teleport just launches forward this playstyle's viability significantly.
Victory Dance isn't very widespread but some of the users who get it are among the best in this meta, made even better with the option of V-Create and Volt Tackle for these mons

I find interesting that out of the normally
banned mons in OU the only one I'm seeing get consistent play is Archaludon, I guess without tera these aren't that crazy but they are still very strong on their own merit and I would assume that with more play and better building these would end up seeing a lot of play.

I find equally interesting that
OU staples like these aren't seeing play at all because of the meta that Alphabet Cup has, Zama is never getting through Pex and Skeledirge, Ghold has no rapid spin or defog to block since most removal is done via Tidy Up, and many of the normally strong mons in OU just don't match up well into this tier nor get a lot of options from it which makes this tier pretty fresh and different from other metagames.
Closing thoughts
I think this tier is cool as hell, I want to see it grow and have OM warriors push it to the heights I know it can get. I'm more than happy to expand on any of the mons and placements I made in this VR so feel free to reply if you want explanation on any of them. Thanks for reading
