Ok opinions (watch out long post):
Supporting Ambipom dropping to D. This thing is so ridiculously easy to take care of it isn't even funny. Any decently built team automatically has at least one proper response to it, if you are running stall make that like 3 proper answers, so basically most of the time Ambipom won't do too much in a battle. Add to that the fact that it is prone to killing itself, has a mediocre typing, barely any bulk and faces stiff competition from several other Pokemon and you get a bad, bad mon.
Weezing should move up to B+. Having Tspikes and Will-o gives it a lot of utility on stall teams, and the meta rn has a lot of mons that are comfortably checked by it, including Doublade, Cobalion, Hitmonlee, Rhyperior and quite a few more, all of which struggle to break through it and are heavily crippled by a burn. Because the meta is so good for it it definitely deserves a little more love.
Rhyperior can go down to A+. Earlier on I disagreed with this, but honestly, Rhyp's flaws are rather exploitable and it doesn't offer enough to be considered an absolute top-of-the-bill threat. It's still one of the most reliable SR setters, but its 4x weaknesses to Grass and Water are very exploitable and it gets worn down over time if you put too much pressure on it. Being a free switchin for Alomomola isn't helping either.
Let's wait with Togetic until after current suspect test to give it a good ranking, we must see if NastyPass stays viable when Yan is out of the meta, otherwise it's solid where it is.
Gorebyss to B rank. Dedicated SmashPass is where it shines, except dedicated SmashPass isn't all that in the current meta, the amount of powerful priority users makes it too risky to use it, whereas just slapping Gorebyss on any team doesn't instantly make it better either, unlike Combusken in NU. On that note, supporting a possible rise for Combusken, thing's pretty baller, faced it a few times and it can really pull its weight due to its bulk.
Saw a mention of Dugtrio rising somewhere but let's wait with that, same reason as with Togetic. In fact it might need a drop after Yanmega is gone.
Doublade should go up to S, I first wanted to say that it should stay where it is but when I tried to come up with arguments I, to my own surprise, was left without any. Whiel it has trouble sweeping actually prepared teams, it is such an amazing staplemon for pretty much any playstyle that one could file it under the "too good to pass up"-category. Even when it isn't sweeping it will cockblock pretty much any physical sweeper for half the game and while yes, its special bulk is poor, it has no recovery and it's slow, it doesn't even really care too much tbh, for it takes non-supereffective physical hits so damn well that it is not worn down as easily as you'd assume, whereas obviously you want it to stay away from special attackers (which shouldn't be a standalone argument against a mon). Shadow Sneak is not amazingly strong but definitely suffices versus frailer offensive teams, whereas it still outspeeds a good portion of the tier's walls/tanks with some investment. Honestly, something that can literally wall so many threats in the tier up to the point where the switches your opponent is going to make are ridiculously obvious and easy to predict, while you can even opt to go for sweeps with it, is incredibly meta-defining and definitely worth S-rank.
On that note, Sandslash deserves to be somewhere in B rank for being the most reliable spinner in the tier rn, giving it more of a niche than it'd ever hope to have last gen.
Clawitze can go to B+ imo, mch like Exploud this thing is extremely hard to switch into due to powerful moves and excellent coverage, becomes even scarier with webs support.
Drop Heliolisk, it's basically just a worse Jolteon with Surf and the ability to somewhat reliably check Doublade as well as discouraging Scald spam to some extent, but generally the C-rankings fit it a lot better because Jolteon simply eclipses it in most ways.
THING I WANT TO BRING UP MYSELF:
Roselia up to B+. This thing finds its niche on stall, where its access to both forms of Spikes as well as Aromatherapy makes it a really cool mon. The reason for why it's so great right now is that it pairs almost perfectly with Alomomola, stall's greatest staple. Being able to switch in on the special attackers that threaten Alomomola is really great, but not only can she do that, but she can immediately put her utility moves to great use, unlike something like Amoonguss. Honestly, this is one of stall's most essential mons imo and definitely should move up to B at least, if not B+.
