Personally I think Weavile is fine where he is. While it is mostly outclassed by Moon (assuming it doesn’t get banned), Weavile has a few key traits of its own. Threatening to OHKO Gliscor with STAB Ice moves gives it an edge in the mu over Moon who has to Tera and carry Taunt/Sub to beat it. Speaking of Moon, STAB Ice Shard is perfect for picking off weakened offensive sweepers, especially Moon. The speed tier of 125 lets it outrun Cinder who often speed ties with Moon. Its frail and heavily support reliant, but it does its job solidly. Now for some of my noms.
A+ > S-: This one is pretty obvious and I agree with this cause Wellspring has been meta defining since last month. Not just its tried and true SD set, but also its pivoting sets and several utility moves like Spikes, U-Turn, Knock, and especially Encore. The latter of which has become a Top 5 move, off the existence of Gambit and slower setup sweepers. Even its checks like Rilla, Amoonguss, and Dnite have their set of problems. Rilla gets U-Turn’d on, Amoonguss is very passive within the Ghold/Gliscor dominated meta, and Dnite can loses its Boots to Knock or get 2HKOd off a predicted switch via Play Rough. Easily one of the best offensive threats in OU only next to Gambit.
A > A+: There is a sentiment with Dnite that alot of people might share but never spit it out. Dnite can basically check the entire tier off of Multiscale, its typing, and E-Speed alone. One of its biggest roles since IoA was being a splashable Wogre check and it has proven to fufill that role better than anyone else thus far. Band sets thrive off the overly offensive metagame while also having the horsepower to truck even physically bulky walls. Offensive and Bulky DD are great, there has even been recent experimentation with Sub-DD which shits on Gliscor. It does suffer from a 4MSS, but it’s so splashable, versatile, and so good at its job that it offsets that weakness. Often times there isn’t a matchup where Dnite can’t find itself good into just cause of how good Multiscale is, especially when paired with Wish support from Mola. Speaking of which.
B+ > A-: Mola is just way too good at its job to be just B+. It does get hardwalled by Wogre without Tera Flying Blast, but Amoonguss is chilling up in A- despite Ghold’s existence. Pivots into physical powerhouses, provides slow Flip Turn, Wish support, and Scald burns. Pairs especially well with Dnite who has an excellent mu into Wogre while it restores Dnite’s Multiscale. Not just a solid defensive glue, but also potent for BO styles. Gambit is annoying as shit, but imagine this thing just healing Gambit back to full. Very few physical attackers can actually one-shot it, and players like Pinkacross have taken full advantage of its strengths, being able to safely bring in dangerous offensive threats due to its sheer physical bulk + Regen.
C+ > B-/B: Beta Bax. Like Weavile, Mamoswine shows how strong Ice STAB and priority Shard is in the current meta. I’d argue Mamo is even better due to its higher Atk stat and lack of SR weakness letting it afford coming in more frequently. Not to mention Ice/Ground STAB is still ridiculous as proven by the late Bax. Even in current gen OU, its 130 Atk stat is still impressive, unfortunately its outsped by Ghold (seriously what was GF smoking with these stat distributions?) and common offensive threats like Valiant and Zama scare it off, so I can’t rank it any higher. However if you are looking for a breaker with decent bulk and priority, Mamo might be a solid pick.
A+ -> S-
C -> C+
(A→S-) : Dragonite is imo S- tier for the simple reason he can defeat any mons from S to A tier, the only threat on that list is Gliscor who's THE S rank when considering tera water+toxic set so your opponent needs to tera even with Gliscor. Looking at other mons Dnite can set up on most of them like Gholdengo, Specs Pult, Rmoon, Valiant, Ogerpon, etc., with the access to encore he can also set up on Zama or Gambit (gambit is more subject to 50/50 though). He's also a good RK to opponent's sweeping mon such as Rmoon, Imoth, Sneasler, WWake, Enam, etc.
(A+→S-) : Great Tusk is indeed suffering more in this meta with Gliscor tanking Ice spinner while clicking toxic+ healing back with tect or just putting spikes and switching Dengo or even just teraing water, he's also suffering from being slower and weak to Ribombee, making it useless to remove Webs and in that case Treads is better to remove hazards. Even though with all these new weaknesses from Dlc1 Tusk remains the best hazards removal in SV OU, I think why Tusk is now A+ and not S- in this list is mainly due to players failing to put the optimal set of Tusk in their teams since it can run many different sets, defensive/offensive BU, booster spinner, Band, AV, are all GREAT sets, (yes AV is very good.) so that said Tusk isn't only a spinner but will also reliably force dengo switch ins and weakening/killing a Dengo can be a considerable progress in a game, Tusk checks Gambit decently, way more than most mons.
(A→B+) : Cinderace is a fake removal, he obviously pressure mon like Glimmora and Ribombee from putting their hazards but it doesn't make these bads and in reality a good webs or good HO will probably still put their hazards in front of Ace since they have a mon to remove them like Tusk or since their others mon can prevent/defeat Ace which makes it a dead slot. Cinderace is even more useless against Hstack teams, he's just forcing them to click hazards twice, doubling turns of a game won't make you win. Race is B+ imo.
B+ to A- or A
A to A- Sneasler is still a silly wincon that can threaten sweeps very easily if prior counterplay is dealt with from its teammates, but some stuff in the tier like Gliscor and Ghold being really popular right now can make it awkward to get it in position to sweep, as it needs a good support from teammates sometimes to take care of those pokemon, as Sneasler cannot really break past them easily at all, and often needs another pokemon to deal with them.
From B+ to B or B- Heatran is a very good answer to Iron Moth, and can provide defensive and offensive utility for teams. However, it still really struggles sometimes due to the nature of how strong counterplay to Heatran is right now as it still sometimes ends up doing nothing in some games, and has a rough time with all the hazards being thrown around and being reliant on tera to do its job sometimes as while better thanks to moth picking up in usage, still suffers from its same problems that caused it to drop out of OU in the first place.
A- to B+ maybe? Hatterene is still a great bulky magic bouncer, however its fellow bulky offensive fairy Clefable is back to give it a run for its money yet again, as while Hatterene is still a great answer to the hazard problem, as a bulky pokemon that hits hard and supports its team it feels a bit hard to justify over Clefable sometimes on certain teams that already have answers to hazards, as Clefable can make good use of unaware and magic guard, along with its expansive support and offensive movepool that allows it to do a ton of things hatterene cannot that allows it to compete for hatterene's team slot. I'm not sure if hatt should drop a subrank, but Clefable being an easier bulky fairy to slot onto teams that can play all sorts of different roles definitely makes hatterene a little harder to justify running sometimes unless you really need hazard blocking.
B to B- or C+ I never thought I would see the day where Toxapex would be outclassed, no less by other options like alomomola, Glowking, Gliscor, Tornadus-T and glimmora, but here we are. As a toxic spiker, its way easier to justify using glimmora or gliscor for toxic spiking. As a bulky regenerator pokemon that offers utility, its outclassed by Glowking, Alomomola and Tornadus-T for the most part in an offensive meta like this. (Albiet it does have haze to stop set-up sweepers and its great defensive type.) Point being, Pex just feels too passive for this offensive meta at the moment, with not enough utility. Granted it still walls some pokemon and can stop set up sweepers with haze, thus why I only propose a B- or C+ drop, but it definitely feels like Toxapex is really hurting right now with all of the pokemon that are easier to run than it that do most of its jobs better without being nearly as passive.
