Quick thoughts on the meta so far:
Ladder has been a LOT more varied than I was expecting going into our second spotlight, which is great! I think a few playstyles (and mons) seem to be doing a bit better than others. SPOILER: these are all my own opinions alone, and as you all know, I am the resident bad take haver :tm:

Probably THE mon when it comes to team building. You should almost always be considering how you're going to break it and how you're going to get the best use out of it (if you aren't running weather or hyper offense). I expect it would probably be the most used by the end of the month if we were to leave the tier in terms of action. I think Chansey is healthy for the tier. Being a Chansey, it is on the passive side, although the ability to rock up or T-Wave an opponent down is always appreciated. Calm Mind Shadow Ball is the set I've been running on the ladder to boost alongside a lot of the setup sweepers in the tier, but this is probably a lousy set due to Chansey's lacking special attack stat (in comparison to Blissey, who sees more use of this admittedly niche set). Many complaints I've seen around this mon surround its ridiculous survivability. While it is true that it is a bit silly, I think we haven't yet reached the stage where it's too challenging to fit reasonable counterplay in Builder. In practice, it isn't very pleasant to see your <insert any strong breaker ever> get walled, but I think adaptations can still be made in play and builder. In my personal opinion, I don't think this needs to go.

I've been running a bit of rain; it's incredibly strong and versatile in the breakers you can choose. Pelipper is the primary choice for setter, although Politoed has seen some use and can be good as a backup setter. Rain requires Floatzel, which finds itself in PU: rain-boosted Flip Turns and Wave Crashes are not fun to come up against, with Jet for priority and Ice Spinner for coverage. Barraskewda is another good choice: importantly, Close Combat and Psychic Fangs gives it far better coverage, notably being able to smack Chansey MUCH harder. The special breakers feel a little underwhelming compared to Barra and Floatzel, but by no means something you shouldn't respect. Golduck, Ludicolo, and Kilowattrel are all strong in their own right, as are the Thundurus formes, which sometimes see use on rain teams, and would probably be busted were it not for the presence of Chansey. There are probably a multitude of other rain-breakers that you could abuse here. Landorus Incarnate, Basculegion, Drednaw, Poliwrath, and Manaphy are all good theorymons, and there are probably others that can work anyway, for example, Flutter Mane (or any Ghost to beat Chansey) and Palkia-Origin. It's too early to say whether Rain as a playstyle is overpowering, but I'm happy to watch it.

I haven't seen much sun, and this is probably because I've seen a lot of rain, but when I have seen sun, it has been destructive. Ninetales in NU gives it the ability to be a powerful self-sufficient Specs breaker in its own right, and Torkoal has good all-round utility (though I think not being able to run Yawn here is a bit of a sadness). The main breaker for sun is Scovillain, who has been ubiquitous with the playstyle since the induction of Tier Shift this generation. However, unlike in May when we first banned sun, there is a bit more diversity in breakers you can choose. The aforementioned Ninetales is scary, and we now also have the presence of the Eruption-spamming Typhlosion formes. Lilligant-Hisui is also terrifying to come up against, especially as it has a limited number of checks once it gets a Victory Dance up. Ordinary Lilligant can also be a menace, although outside of sun, it suffers from a lack of coverage. Charizard gets a worthy mention here as well. I don't yet think sun is at the level of overwhelmingness as rain is. However it is undoubtedly not a playstyle to underestimate. I think Scovillain is particularly strong.

Webs HO is extremely scary to come up against due to the tier's nature and the many viable setup sweepers. It does not help that we lost our best unaware (Skeledirge) to an OU rise. Webs, in general have been strong across all tiers this generation due to the lack of good removal, and it is no different here. I think it's certainly something to keep an eye on, but even if it did become broken (which I don't foresee happening yet), I'd have no clue how to tier it. It would probably be saner to ban the more ridiculous sweepers, ie

Shell Smash is broken; it does not help that King's Rock is free. I think Cloyster has an advantage over its competitors: Polteageist struggles against Chansey without Tera around, and you'd have to make unreasonable adjustments to get past it (run Sub and pray the Chansey isn't carrying Shadow Ball). Drednaw has a slightly worse ability, and you can't run King's Rock due to not having Skill Link, although if Cloyster does end up being banned at some point, I will be slapping Drednaw in as a direct swap.

Stall is thriving, thanks to the amount of hyper offense flying everywhere, and it actually has a decent amount of tools at its disposal. Chansey is mandatory. Gliscor is actually very decent here, as it can spike up against a lot of neutral hits and generally be a nuisance to the rest of the team. Chuck in a spin blocker, for example, Giratina (I like Sinistcha and Dirge when it was not OU), and you already have a decent core. I like Unaware on this core for the setup sweepers (which is why Dirge rising SUCKS why does OU steal all the good things its not even fun OML). Even with Dirge gone, there are still decent options, such as Dozo, Clodsire, Quagsire, and Crocalor, if you're willing to either sacrifice bulk for boots or commit to keeping hazards off. This is an extremely good playstyle and decently enjoyable. Still, we'll see if the meta adapts more to it: all of these mons noted above can be taken advantage of decently, and the tier does have decent raw stall breakers (see: Ursaluna and Heracross).

where are all the balance teams LMAO
None of my teams have been extremely successful, but I peaked at 1450 (around #20)
and promptly tilted, but we don't talk about that
If you want to use the teams of the resident bad take haver, here they are:
https://pokepast.es/cb8850bb9762bdf8 - out of date due to Dirge rising. Giratina + Dozo is probably better than Dirge + Corv anyway here. The idea with this team is to hazard stack and then withstand whatever your opponent throws at you. Phazing might add another level of horror to this team (free Skarm)
https://pokepast.es/7c52b3e47473d091 - basic webs team. Flutter is EV'd, so sub doesn't break when uninvested Chansey SBalls when you are at +0. Hoopa and Flutter are both sub, in fact, and stop Webs from ever being spun off (positioning a Defogger is possible against this team but is mightily difficult). Cloyster does Shell Smash is Broken every time it gets a chance + Flinch Hax :TM:. Ursaluna is one of the scariest breakers in the tier, and webs enable it to not care about its awful speed tier. Houndoom is here because I kept on getting owned by the Sun teams mdr
I was running a rain team, but I did not come up with the initial structure, so I will not be posting it here. However, I think pretty much anyone can look at the available tools and build a semi-decent rain team LOL
