A quick nomination in this thread for now, I was planning to wait until the discussion points came out but I wanted to get this nomination out of the way. I’m posting on mobile so sorry for the eh quality
(C to UR)
In my opinion, shuckle is virtually unviable to use in the current metagame, being wholly outclassed by ribombee. I’ve experimented a lot with the webs archetype as my new method of cheesing the ladder since screens got the boot, and ribombee outclassed shuckle as the webs setter to an overwhelming large extent to the point where it should be UR. Shuckle’s inability to pressure common defoggers and hazard removers like Salamence, tentacruel, starmie, hatterene, and the washer as well as its ultimate passivity for setup sweepers like sub keldeo and aegislash makes it too hard to justify compared to ribombee, who is much more reliable due to it being able to pressure hazard removers, having an actual offensive presence, and still being valuable against the poison and steel-types it cannot touch via stun spore. You are always better off running ribombee + LO krook or necrozma as a rocker rather than compressing the roles with shuckle, it just is not worth it. Overall, shuckle’s role compression as both a webs and rocks setter is not enough to justify it having a rank, and thus should be unranked.
To quickly visit the other “discussion points” rain is very inconsistent and more of a MU fish than anything. I haven’t been able to build a consistent rain team and the unreliability of the archetype doesn’t warrant a rise for me. Not to mention, it’s not all that good as many have made it out to be. Disagree on fires like Moltres and rotom heat rising, yes the grasses are rising but so are Pokémon Like Salamence, Glowbro, galarian Moltres, and Nihilego that can beat them. I talked about this when I nominated rotom-heat to drop, but basically anything these fires want to do can just be done by mence who struggles less in the current meta.
Arctozolt is indeed cool and funky

Already being a more niche pick, but can check Sneasel, however doesnt posses any reliable recovery and with Spikes up can be wear down even faster
Defensive Buzzwole is probably the best check to Sneasel, high defense and hp stat, Dark resist and instant recovery on Roost, but must be aware on constant switchs on Triple Axel + Stealth Rocks and don't catch a Toxic from other picks.
B -> B+
B -> B+/A-
POST-THUNDURUS VR 
enthusiast, king is scarier but queen finds its place into teams more easily. I tend to value the other ground types most of the time.
can probably end up in B/B+, I'm not super high on it cause its flying stab is awful and you have to rely on it hitting a lot. Choosing a 4th move is insanely painful since you'd ideally want GK, Superpower, Heat wave AND a reliable stab (air slash??).
from B+ to A-: Necrozma is rising on account of its many offensive applications and the restricted counterplay it has between its many good sets. Stealth Rock + Meteor Beam sets offer a lot of great utility and role compression to offenses, though its DD and CM sets can also dismantle ill-prepared teams on many occasions thanks to its expansive coverage movepool. Although it can feel a bit understated at times, Necrozma certainly possesses the blend of utility and offensive prowess necessary to hack it in A- right now.
from B to B+: Seismitoad has been a pretty solid utility pick for some time now, offering an excellent Rotom-W matchup as a rocker while additionally checking foes like Nihilego and Jirachi quite well. Its ability is nice for dissuading our many Water-type breakers from spamming their STAB moves, its movepool can yield some surprisingly useful tools, and its role compression is certainly enough for a rise at this stage.
from B- to B: There isn’t really much to offer about this rise that we didn’t cover in the last update. Volcanion is simply just a strong pick for a wallbreaker that was previously overlooked, offering neat tools between its set versatility, capacity to check foes like specs Primarina and Entei, and the difficulty many teams encounter pivoting into Steam Eruption with Salamence trending downward and Kommo-o taking over as the tier’s “main” Dragon-type.
from C to C+: Articuno has a well defined niche on fatter builds that is worth placing it above the rest of C. A decent matchup against other stalls, great bulk that lets it check Roserade/Primarina/etc, and a fantastic supportive movepool are all among some of the more notable qualities that enable its rise to C+.
from UR to C: Crobat has carved a niche as an option for both hazard removal and Speed control in recent weeks. It matches up well against the Roserade/Buzzwole core running around and has an excellent Speed tier for the meta, though it still has plenty room to be further explored in the coming weeks given the several interesting utility options in its arsenal, and I guess Nasty Plot if you’re 
from UR to C: Lucario’s 4mss and competition from other Fighting-types still hurt it a fair bit, though its ability to pressure the many slower teams running around also can’t go unnoticed. Swords Dance presents a good amount of prowess between its power, strong priority, and capacity to bypass paper checks depending on the coverage it opts for. Although it requires its fair share of support, Lucario certainly has the offensive toolkit to succeed in the metagame and could certainly define a clearer niche with more time for exploration.
from UR to C: Regidrago is a decent anti-meta pick with a pretty underrated but nasty offensive prowess. Choice Scarf offers incredible power and the ability to surprise many common Pokemon with its enhanced Speed as evidenced by the replays provided in pif’s 
enjoy!
from S to A+: Aegislash may be still excellent, though the VR team seemed to be in agreement that this stage of the metagame doesn’t currently warrant an S rank. While still among the most consistent picks in the tier, it isn’t the same domineering presence it once was, especially as Pokemon that can take advantage of its flagship Toxic set like Roserade and Celesteela come into their own. It’s still important to account for in building, but has developed to a state in which many teams are more than prepared for its most potent set.
from A+ to A: Although it is still a fearsome offensive presence, Lycanroc’s wallbreaking capabilities don’t feel as accessible now as in months past. It struggles to pick up kills as efficiently while Buzzwole/Scarf Jirachi/Celesteela surge and foes like Amoonguss and Aegislash maintain strong spots in the metagame, complicating both its durability and 4mss.
from B to B-: There isn’t too much to elaborate on with these two dropping. Their reasons for rising to B were specific to their niches on rain builds, so with their preferred archetype falling out of favor lately it only makes sense for their ranks to correspondingly lower.
from B to B-: Obstagoon has been a bit of an awkward pick for quite some time now. Despite its impressive damage output, it generally fails to perform any given role that is to-die-for in teambuilding, especially given the utility other Dark-types like Krookodile and Zarude offer. As Buzzwole trends and Aegislash becomes less immediately urgent to check, it makes sense for Obstagoon to drop from its long-time place in B.
from C+ to C: Incineroar barely clings onto a niche on account of its ability to blanket check foes like Aegislash and Zarude. However, it has suffered many flaws for quite some time now. Keldeo/Kommo-o/Primarina all being top-tier breakers really eats into its consistency, while it also suffers fairly notable competition given the high amount of other Dark-types that currently offer a lot of utility and teambuliding value.
from C+ to C: Klefki has it a bit rough as a Spiker that often fails to carve a spot on teams over Roserade or even Froslass, as well as a Steel-type that suffers immense competition from many steadier options, like Aegislash and Celesteela. Its typing can still be pretty clutch in checking Roserade, Zarude, Goltres, and various other foes, though, which helps it cling onto a rank alongside the unique perks its movepool and Prankster lend it.
from C to UR: There really isn’t much reason to use Milotic lately given the bevy of strong options for bulky Water-types that just offer way more utility, whether that’s a more practical ability, a useful secondary typing, or more meaningful movepool perks that let them stand out more.
, but your claims seem to be fair convincing. Nonetheless, I think this pokemon is in an odd position right now because of the introduction of 
to the tier, as it is one of the best Spikes setters even in OU. You said that 
?
UR -> B-
252 SpA Choice Specs Porygon-Z Thunderbolt vs. 252 HP / 252+ SpD Slowking: 204-242 (51.7 - 61.4%) -- guaranteed 2HKO
New to B+: While not as good of a Rocks setter as the mole, Swampert is still a solid choice for a Rocker. Water/Ground is an amazing defensive typing, it can make progress by pivoting, and Yawn/Toxic support is great.
B- to B+/A-: Gee wilikers, a tier shift that caused a large amount of Dark and Steel types to drop makes the Fighting types in the meta better! Who would've thought? In all seriousness, Conk is kinda crazy right now lol. The meta has shifted heavily towards fat/balance teams, and if there's one thing Conk is good at, it's shredding balance teams. We also got Slowking in these shifts, who is a really amazing partner for Conk since its Future Sight blows holes in whatever Conk can't break. Pif made a really good post in the NP thread highlighting why Conk has gotten so good lately, and I recommend checking it out. The jump may be too big, but IMO Conk really deserves it right now.
These two should definitely be ranked. Goli carves a niche for itself as a Spikes setter with powerful priority, and PZ is basically the special attacking version of Conk, able to shred fatter teams without blinking. They both have their merits and should be ranked to reflect those merits.
