It's clear that tiering action on Tera didn't win because
Finchinator didn't shore up the blue wall and visit Michigan.
Jokes aside, the result is disappointing, but understandable. Thanks to the mod team for running a thoughtful and fair suspect. There's not much to do now but move on and keep making the tier better. The seething and gloating over the result in this thread seems pretty childish. I get having strong feelings about the decision, but try to keep some perspective and remember that this is a game above all else. It's never that serious.
Moving on to some of the stuff on the radar:
Chi-yu has the clearest case for a ban in the post-Palafin/Bundle meta. This thing is just far too strong and oppressive with no real switch-ins outside of a few vastly inferior choices like Dachsbun or Tyranitar. Though a quick ban seems likely, it should be first on the suspect list otherwise.
With Tera sticking around, I think this is another fairly clear case for a ban. Lead and Resto Chesto are good sets, but bulky Taunt with Lefties just absolutely obliterates so many builds and is made even stronger when you can defensively Terastallize to bypass any check. Annihilape's fantastic bulk and Rage Fist means most teams, even offensive ones, have to play extremely carefully around the ape, especially if Tera is still available. Even then, there's a decent chance you are losing 2 or 3 Pokemon to deal with a well played Annihilape. This is another one I hope to see quick banned, but should be a suspect contender if not.
I was originally in favor of a Shed Tail ban, but Orthworm's suckage has changed my mind. Cyclizar is the problem as it has absolutely everything it needs to enable a bunch of ridiculous sweepers. Regenerator allows Cyclizar to pass multiple Shed Tails with little downside which is coupled with excellent support options (Taunt, Rapid Spin, Knock Off) and insane speed. Offensive options (Draco, Overheat) are really lackluster, but that doesn't matter when you can just pass a sub to anything instead. This is the final mon that I hope to see quickbanned over suspected.
Garganacl has incredible bulk, status immunity, and a wonderful move in Salt Cure. You pair all of that with the ability to Tera into any number of viable types, and Garganacl takes up a fairly uncommon position as a mostly defensive Pokemon that may warrant tiering action. All of the tools Garganacl has at its disposal allow it to take on pretty much any Pokemon in the tier, but it is quite reliant on Terastallization to do so. Though I think its still a little early now, once some other bans drop, I think Garganacl could find itself in a position where it warrants a suspect/ban.
I don't know what it is about this Pokemon, but it seems to bring out some of the absolute worst takes from people. My favorite has got to be the people who claim that Gholdengo "brought hazards back" and should stay so people can't "mindlessly remove hazards". First off, hazards have been an extremely relevant part of every generation since GSC. They are arguably least relevant in SS thanks to HDB, but HDB exist in SV too. Second, to imply that hazard removal comes with no downsides (that is, mindless) is just blatantly incorrect. Third, we find ourselves in a hazard meta that is much more akin to BW (where there aren't removal options) than SS (where there are removal options), despite the fact that there are some good removers (and HDB) this generation. Now, Gholdengo is not the only culprit here, as the increased distribution of hazards is a major factor too, but it is still quite clear that Gholdengo has shaped this metagame in a profound way.
No, I don't think Gholdengo is inherently broken, but it is an extremely centralizing force that warrants a closer look, probably even a suspect. There is no Pokemon in the tier that does its job as well as Gholdengo does its job of keeping hazards up. This kind of presence is useful for almost any type of build from HO to stall and is further backed up by Gholdengo's great stats and typing. I think a pretty obvious example of Gholdengo's influence is the dominance of Great Tusk (and Iron Treads to a lesser extent). Tusk is a top tier Pokemon for sure, but its usage is at almost 40% because its the only removal option for a lot of teams because it can spin and beat Gholdengo (sometimes). I also think Chi-Yu's imminent ban remains an X factor here, as its one of the best offensive checks to Gholdengo. Its ban could bring even more Gholdengo usage, though that remains to be seen.
