These are some great bans! I'm happy Dragonite is gone, I feel like it was a really restrictive presence on the metagame. Personally, I found Glare more annoying than anything, but it will be nice to not have to account for it when switching in on Goodra-Hisui or Gliscor and make one less thing to consider when teambuilding. Tera ban has the potential to be good as well, that extra bit of stability will make the meta a lot more digestible.
Here is my new threat list! These are all things I think we should keep an eye on. Ranked in threat level from top to bottom.
Urshifu-Single-Strike
Hey everyone. Did you know that both forms of Urshifu are legal in this? It's a little fucked up, but it's true. Urshifu-Single-Strike was number 2 on my shitlist before Dragonite was banned, and it has just risen to number one. It doesn't gain much from Alphabet Cup (Knock off and Upper Hand) but it doesn't really need anything in order to become completely unanswerable defensively. While it lost the ability to Tera Dark to get those 2HKOs, everything else lost the ability to Tera Fairy, which is probably a net benefit for it. This might not be as well known if you haven't played with this mon since Gen 8 OU, but Urshifu also has SD this gen, letting it completely beat down defensive mons (tera-less Skeledirge or bulky intimidators like defensive Salamence are not enough, Burning Bulwark doesn't work either) while taking out offensive mons with a boosted Sucker Punch. I didn't really comment on it earlier cause I sort of assumed it would be quickbanned at some point, honestly. Please consider that.
Iron Bundle
Stupidly fast mon with strong neutral coverage. It doesn't need Specs to blast through offensive mons slower than it (most of them
are slower than it), but it certainly helps against specially-bulky switch-ins. The closest thing to checks to this mon are special walls that aren't weak to its moves, namely Blissey, Slowking-Galar and Goodra-Hisui. Maybe some more niche mons like Muk-Alola or Snorlax as well. Even still, these mons take enough from Specs-boosted neutral hits that hazards, crits, even chip damage from Flip Turn can put them in range of 2HKO. Against offense, it basically just gets into a favourable position and clicks buttons, but it might find it a little harder to manage to do with my predicted influx of priority-using sweepers that were previously too dominated by Dragonite to succeed. Either way, Iron Bundle is such a menace, it has way too much speed and power at its disposal.
Ninetales
V-create should probably have a spurious gaze cast on it as well. The best V-create user imo is CB Ninetales, which is almost a Dracovish-esque breaker that does about 47-50% to phys def Toxapex with its main STAB option. This is obviously completely ridiculous for most teams to switch in on, and almost requires even bulkier Fire resists like phys def Intimidate Salamence, changing the weather with Pelipper (watch out for Volt Tackle!) or Tyranitar, or even just straight-up immunities like Heatran. The main shortcoming of Ninetales is that it's super matchup-dependent. Offensive teams often just outspeed it and kill it easily, and while the threat of Scarf is there as well, I feel like Band really allows it to find a good role in the metagame. Ninetales's level of brokenness, like these sort of exorbitantly powerful breakers often are, is really debateable because of its matchup-dependence.
Volcanion
Volcanion is the other main V-create user. I'm sort of hesitant to say Volcanion is close-to-broken on its own, as it really kinda just makes use of two borderline moves, being V-create and Victory Dance. CB Volcanion is a good breaker, not quite as potent as Ninetales on its own but it can come in a lot easier thanks to its defensive qualities. It can take out some Fire-types a little easier and also generally fits better on Trick Room thanks to a lower speed tier. The Victory Dance set is kind of the more threatening set overall, with a ton of power and tricky to revenge kill after a boost as well. It's got its checks for sure, but even they can be overwhelmed after some boosts, and the lack of Tera Dragon to put your Corviknight into a state where it resists all of Volcanion's moves will make it even more difficult to manage. Although V-create can put Volcanion into a revengeable state, that's usually after it's managed to take something out first. This is one that I feel like will definitely improve with the most recent wave of bans, we should keep a close eye on it for sure.
Salamence
Salamence was never really bad so much as somewhat overshadowed by Dragonite. Now, Salamence is poised to become one of the best sweepers in the meta. Like Dragonite, it boasts powerful Flying STAB, but it's arguably even more versatile, making use of so many S moves (Scale Shot, Sacred Fire, Stone Axe, Swords Dance and more), not to mention Bitter Blade and Bolt Strike from B, among others. This results in a supremely customizable setup sweeper with strong STAB and a ton of quirky coverage, a Scarf revenge killer that can spiral out of control with Moxie, or a solid defensive mon with Intimidate and some great utility options. The main saving grace is, unlike Dragonite, you can check it with a priority user... unless it Sucker Punches you first, I guess.
Urshifu-Rapid-Strike
Haven't even seen this mon much, I'd imagine it struggles much more with common bulky water resists like Toxapex and Amoonguss and is more vulnerable to contact punishing. It also is very hard to handle after an SD and even gains Knock Off to remove helmets on CB sets. I'd also like to mention that Future Sight from Slowking-Galar is still viable support for either Urshifu in this, although I find that it generally struggles to connect with Toxapex as easily thanks to Teleport.
Ursaluna
Trick Room is viable in this meta, with new setters and abusers. I think it's wise to keep an eye on it, as TR pivots like Toxapex or Ting-Lu, as well as OTR Ursaluna, not to mention powerful slow threats like choiced Volcanion, Primarina, or Araquanid all give the playstyle legs to stand on. Ursaluna is of course the crux of Trick Room, being able to set it up for itself and its team and leveraging so much power. There have been times where I've played against it and felt totally helpless, but the banning of Dragonite should allow more room for other offensive priority users in the meta that can hopefully pick off a worn-down TR sweeper.
Ursaluna-Bloodmoon
More broken bears. Doesn't really gain anything from this meta and doesn't need to. This mon is a bit low on the list because I'm not 100% sure about it, it felt hard to use before the last wave of bans as it tended to turn over a lot of momentum to Dragonite, now it has the potential to feel a lot stronger against a variety of teams.
Cinderace
Cinderace is probably one of the top offensive mons you can use. It can hit pretty much any switch-in hard with its strong coverage, or chip it down with U-turn, or set up or clear hazards, or get a burn with Sacred Fire, or any number of rude things. With Libero and such wide coverage, it's really capable of 2HKOing pretty much anything on a CB set with the appropriate move, so you need to scout it first lest you lose your wall to some weird move like Crabhammer or Supercell Slam or something. Really annoying mon.
Hazard spam

Hazard spam + gholdengo was a very successful team composition, now with Glare banned Gholdengo has fallen off some. In general, experimenting with Tidy Up and Court Change users helped me play around this, but even still, against a good player, it was really punishing to be able to find an opportunity to clear hazards and I was often unable to recover.
Other victory dancers


There are other viable Victory Dance users as well, and they are all capable of using V-create for powerful coverage. While I don't feel strongly that any of them are really broken, they can be really difficult to manage for offensive teams relying on physical priority moves to check offensive threats.
