My VRs post-SPL. Worth noting these are based on tournament games/prep rather than ladder. I also only included Pokemons I actually used/tried/tested with over the last 4-5 months, which is why some Pokemons I consider viable won't be featured.
S-Rank

I like Thief a lot to limit other Skarm's longevity and if you're not facing Skarm, it's likely going to be useful anyway. Just requires more finesse. I also like OffSkarm on fat teams for the odd Magneton match-ups. Not a fan of Taunt in general, it's mainly useful against other Skarm but they will usually find ways to Spikes anyway. Can work on fast pased SkarmOffenses though.

Max HP Bold Blissey is actually incredible. At the cost of IB, you're now much less pressed by pretty much the whole tier and also do a much better job checking the mix attackers like Mence or Salamence. Wish and Cleric are two of the best moves in the tier and enable so many sets/Pokémons, and Bliss is tied with Jirachi as the best Wisher and the best Cleric by far. CM Bliss is also excellent but I think it requires back-up Special checks on the team as otherwise it's too easily abused by a lot of Pokémons without the threat of status.

Sand is just too good. Weird mon to use right now because a lot of meta advancement has been done with beating down/trapping Ttar into weather reset, which is very strong into a lot of TtarSkarm offenses. PursuitTtar also has a unique spot in the metagame that can't be quite filled by anything else and enables a lot of other Pokémons/teams. I like most sets besides the Mixed one. SubTtar probably deserves more usage, as it can be protect itself into sack+Dug plays and is a good breaker in general.
A-Rank

I think Wish is one of the best move in the tier, and works excellently for me and the way I play. Much like Spikes, it makes every Pokémon better, and Jirach is the best user of it. Besides that, I think it has a good set into any team or playstyle. I rate pretty all of its sets besides the Mixed one. I think it's also better than ever in an era where a lot of people are including Suicune in their build, as Jirachi works very well against it in Sand but with a better snowball potential than other Pokemons used for the job. Wish Rachi one of the best Pokémon to have against Skarm teams, which are historically the most consistent teams in the tier.

Hard to go wrong with Meta, although I find it too eratic as a stand-alone offensive piece. I like it a lot alongside good old Mag to enable better Boom targets for your traditional offenses. Also good on balance as a better offensive ramp than other Rock resists and it's not like Skarm cant touch it so you're advantaged long term if you have your own spinner. Boom is a free out of jail freecard if your defense got overwhelmed. AgiliGross still very good to me. Don't like the Mixed sets at all.

Just very sturdy and consistent with an awesome package of move. I rate Curse as a filler to turn the tables on Cune. EndPert is an awesome momentum reverser on Offense.

I like most sets. I've become a fan of SubDD Mence, it's very good into all these Sand-less builds. Also really useful in all those situations where people will control Mence by sending Claydol and boom on it in the late game. Clutch into TW + Ice/Boom in the back or ToxicPert/ToxicRachi as well Just not a fan of CB. It's often hard to navigate into a safe endgame vs DDMence honestly.

Most flexible spinner by far. Second check to pretty much everything in the tier, just a very reliable 'mon and while I do find it passive, it still rarely disappoints me when I use it. Big fan of Wish alongside it to play the long game vs most Spikes build.

I like all the Rest sets, Calm Cune really shifted the meta imo as it's so good into a lot of its checks. Not much else to add here. Roar Cune is still good but very support reliant, as always.

Very low on Zap atm, I don't like how it doesnt have a clear defensive role vs most of the tier. I like more specliazed Pokémons. I used to be high on SpDef Roar Rest but it's awkward to use (Rest sucks) and also thuds into Claydol/Pert so needs the right support. I'm also not a fan of the team it lands itself on at the moment. I still think it excels as an offensive ramp for offense and that's where it shines the most. Although, even then, you're sometimes missing the extra wallbreaking/offense checking that Zapdos doesn't really provide. It's also less solid into Cune right now with all those Calm and IB sets floating around. I also think it has the same issue as Moltres in Blissey is often suffocating for it, and nevermind Claydol pivoting/spinning on it. Still think it's a very reliable 'mon, but feels like a jack of all trade master of none to me right now. I have yet to experiment with the BP Rest and Sub Rest sets though and maybe there is something big to discover there.
B-Rank

Great for offense, same old. Heavily dislike EQ-less though (or at least Focus Punch).

Very good but not a big fan of Dug Offenses and while Dug Defenses are some of the best teams of the tier, they often feel quite inflexible in term of playing, not to mention limited in building options. The ability to accurately gameplan with Dug is unmatched though, and it just checks/enables too much.

I still like 3atk Leech the most as it's a very strong 'mon in the early game to put the pressure on. The defensive sets are plagued with the same issues as ever, but ironically they're also the best check to the 3atk Leech set so I often tried them. The BP sets are either gamebreaking or shit. Solid but too easily pressured for my liking. As an offensive mon, it's sort of checked by all the physical mons of the tier. I rate it but not too much. I think Protect deserves exploration on it, pairs well with Leech and reverses the momentum vs Aero. Toxic is also interesting to me because it heavily punishes a lot of pivots for it.

When you think about it, the only Spinner that doesn't freely invite Skarmory to switch in and get free leftovers heal and its spikes back. Also good at switching into passive mon thanks to Natural Cure. I quite rate those traits despite its overall passivity. The offensive sets are also nice even tho I'm not the biggest user of them. Very solid spot in the meta imo much like Claydol.

Quickly discarding Skarm is just too good. MagSpin also keeps a lot of fattish build in check and force people to be paranoid/renew themselves here and there.

We know what it does. Personally I'm not the biggest fan because I think it's a win-more kind of Pokemon. Either you're even or in the lead and Aero will checkmate your opponent in a lot of situation, or you're behind and it won't be able to reverse the situation (I don't mean those games where you're one or two flinches away from winning). Definitely good to use here and there so Celebi doesn't get too cute vs you though.

Same issues as ever to me, just not kind my jam even though I reckon it has the toolkit to influence games like almost nothing else. I ought to explore Wish support with it because now all the little chip you may take wouldn't be as crippling for late-game scenarios. Technically though, there is no unplayable match-up with Gar, but that's not really how I like to play/prep and find it super awkward to use almost all the time. Its best progress maker is also still a 75% accurate move.

I don't really rate fattish builds with Forre as the sole spinner, as those are too inflexible in term of gaming and Forre feels like it has way too much to do for them. However it's solid alongside another spinner and can use its nice kit of moves to effectively trade into Spinners or cripple Skarm.

Not super flexible in term of building but just very good at checkmating so many Pokémons, like nobody else in the tier.
C-Rank

I rate its unique ability to be a solid Rock check immune to Spikes, but I'm low on Superman builds so keeping it down in the VR. I've tried CB a little bit more this time around and its interesting in the builder but CB EQ is too often a very awkard Stab to click. Not reliable enough offensively for my taste.

Same as ever, maybe better to me in a time of high Suicune usage, but otherwise I wouldn't say I discovered something new here. I think it's nice balanced teams in a similar spot as DDMence where you're not using Mag but just gunning for an endgame after you've weakened everything. Gyarados ability to pivot/check Cune and Pert (without risking an OHKO from IB) is very good on these builds.

Excellent self-sustaining breaker. Much better in Tournaments than ladder imo as most people will respect its OHKO potential more.

Not much to add here. I know I rank it worse than a lot of people but personally I think it lacks a tiny bit of power of power for me as a lot of Pokemons can pivot into the fire moves and then afford to stay in and trade with it. I probably ought to try it more though.

Same as before to me. When I use it I tend to really like Protect + Status to push the issue into a lot of its checks and prefer to deal with Blissey through double checking than Roar.

Still a nice early-game pressure imo, but hard to find value past that and if you have to sack it early, then your advantage of playing vs a slept mon may not amount to much if the opposite sleepy mon is just sent as a sack too. I like Sub a lot on it to delay the sleep and get more mileage out of it.
D-Rank

Honestly I just almost always prefered using Medicham or Breloom. Megahorn being such an unreliable move sucks too. The Fire weakness stinks compared to Medicham. Not an awful Pokemon by any mean but personally not much of my jam.

I'm not a big fan of Spike-less Hariyama fat at this point, these teams feel too slow and too reliant on Hariyama to break through defensive teams. Solid pick into standard sand I have to admit, but kinda weak vs the rest of the meta.

I often found myself experimenting with it as it's such a nice role compressing 'mon but felt hard to justify over Jirachi most of the time. Still think it has a lot of room for exploration on Offense as a unique blend of steel typing that isn't pressued as much by Zap or CMers compared to Rachi.

I respect what ABR has done with it a lot here, it's such a nice physical check with a much better match-up into Fire types, MixMence and Zapdos. Think it has solid days ahead as more than just a Metagross-look-alike on Mag/Boom Offense. Still find it awkward because of the water weakness and the weaker power.

Not much to add here.

Neither here. Personally not a big fan as I feel like it gets too low too quick, hates status, and is too slow to make good use of its access to Boom. Stab IB + TW is hard to play around a lot of the times tho, and I respect it for that.

Really not a fan of this on typical teams where you could use Skarmory instead. Just super awkward to use imo. Cute into offense though as a way to trade something while getting that crucial spikes up. Pairs well with Trappers and I like the interaction of Boom into Mag vs Skarm, or Boom into Dug vs a lot of other things.

ABR has done wonders with it in recent months but personally I haven't explored it too much so I'm gonna keep it where I usually rank it. I always thought being the fastest CMer in the tier, without any weakness to other special mons was a very strong combo of options and I could probably try it more.
E-Rank

Always a good Pokemon to keep in the back pocket for its insane match-up into Claydol and Starmie fat, as both styles are often seen so for that reason alone, I've often considered it.

I think its niche is quite easy to find in general and I also often considered it for this reason. I especially like how it matches into offensive Celebi which is the bane of a lot of defensive teams that won't use Mence, Dug or Aero. Add Jirachi-checking to that too. The main issue here is that, as a Knock Off user, many Pokemons that switch into it are immune to Sand, which delays the progress it'll make on a given game (Pert, Meta, Ttar mainly). On other hand, if you're spinning with it, you will probably want Mag or strong anti-Skarm measure, and it will also be awkward to use as it hates dealing with WoWGar and Skarm long term. Awkward mon.

Same as ever. Would like to add it can be nasty in the backline when you're trading early. Think CB Gross into Jynx to quickly create a 5vs4 situation.

I don't rate Smeargle Offense super highly, I feel like the cost of using a Pokemon that will often not do anything but get one, maybe two spikes into a team that can't play the long term, won't be very good. Not to mention that you're gonna be stuck into weird mindgames vs Spinners. And that's not mentionning the potential nightmare situations where you run into Lum user. Def worth bringing once in a while but never really felt worth it to me.

Honestly not too bad, hard to justify however when compared to the other Fighters but it has that unique blend of bulk/power/higher speed than Hari that makes it unique and usable.

Might be overrated as a Spinner that is such a rock solid check to Ttar/Aero and also solid into a bunch of other physical attackers (Meta, Mence, Gyara, can trade with Fighters too). It's still tight to build with it, and also feels quite awkward in a lot of match-up where you don't have the Boom threat of Claydol.

Same as ever, may be worse atm if anything bc of Suicune usage, and even Starmie has been on the rise, or at least it was in SPL.

Honestly pretty nice, it's solid into Dol much like Missy but feels more useful outside of it with the combo of Knock + Toss. Still very limited vs non-fat teams ofc.
