I'm just going to quickly address all the drops that we have received recently, but I'll almost certainly cover how the rises have/will affect us once the meta has developed more:
I think most people already know my stance on this Pokemon, but it's certainly a similar one to the one I had when Hariyama was in the tier. The issue is, it has a very healthy defensive set for more stall- and balance-based archetypes with not being susceptible to Taunt and essentially being an alternative, or even better, Audino, thanks to an arguably more useful typing; although no Regenerator can be a pain. It'd even help versus things like Bulky Oricorio Sensu, which quite literally eats stall alive. However, it also has what is arguably one of the most broken sets to ever "grace" PU, which is its Nasty Plot + Z move + Trick Room set. As previously stated Aromatisse is unable to be Taunted, and alongside decent bulk and the limited Steel-types in the tier, means that it has very little trouble in being able to set-up and sweep, or at least break down the opposing team at the very least. If this thing stays in the tier, not only will it see far more unused Pokemon that don't really have a niche (and shouldn't have one) being used, but it'll also degenerate into what happened in NU with Cofagrigus, which will be people purposely lowering the level of their Aromatisse to stand a better chance against opposing ones. This Pokemon needs to be banned as soon as possible.
Now I'm not sure what my stance on Omastar actually is, because I do agree that some builds are pressured too much by its Shell Smash set, especially if they get the Weak Armour proc. However, unlike with Aromatisse, I don't really think that Omastar is unhealthy; quite the contrary, I think all of its sets are actually a healthy enough addition to our metagame. The offensive set isn't as bad as people are making it out to be, especially with a decent amount of checks available. It isn't actually too fast even at +2, with Pokemon like Choice Scarf Lilligant, Togedemaru, Primeape, Pyroar (which will be on the rise as of the most recent shifts), etc. all being able to revenge kill Omastar. Even Pokemon such as Gurdurr and Hitmonchan put decent enough pressure on it with Mach Punch. I do see the argument for the offensive set being potentially overbearing, as almost all of the tier falls to a +2 Hydro Vortex, even specially defensive tanks like Assault Vest Hitmonchan, but I don't think that it'll be nearly as bad as what Aromatisse will do to the tier. My stance on the defensive set is that it's actually a fun and decent check to Normal- and Flying-types, with good utility choices and a way to beat the other soon-to-be common Spike setter, Qwilfish, in Earth Power.
The other Water-type that dropped, and what is arguably going to be the most talked about and prominent (healthy) drop. Qwilfish made a big splash when it was first introduced after PU Beta, and helped to shape a large portion of the then-current metagame. Even though I wasn't the biggest fan of Qwilfish, it will certainly shake up PU far more compared to what was becoming a stale meta populated by Ferroclef + fillers. Qwilfish will finally breathe life into more offensive teams with its fantastic utility and a great typing, alongside the coveted Spikes. Qwilfish will also benefit other archetypes, especially balance, with the previously mentioned utility. I think, more importantly, is the fact that Qwilfish acts as a Kingler check, which is basically invaluable in a meta that has lost both Gastrodon and Ferroseed, even if the former was only a soft check. My only gripe with Qwilfish is that it does encourage rather lazy building in some cases, same as with FerroClef did, but I'm certain that it'll shake up the metagame nonetheless and encourage more offensive archetypes to make a comeback since both Archeops and Magmortar got banned.
Altaria is certainly a welcome return to PU, with it leaving at a bad time for us, especially when it was during the "reign of Magmortar", but it returning will only help bolster both stall- and balance-archetypes. We've been at a loss for hazard removal, especially more reliable Defoggers, but Altaria dropping changes that. Several utility options alongside both reliable recovery in Roost and a decent enough defensive typing will help against the Spikes filled meta. However, Altaria currently loses to all three of the new Spikes setters unless it runs a move like Dragon Pulse, which might be more common since it only required Flamethrower for Ferroseed. I don't have much else to say about Altaria, but I'm happy NU has stopped using it post Emboar ban, since it was virtually useless.
I've been hearing rumblings about this Pokemon being "broken", but I really don't see it at all. Yes it does have a fantastic speed tier and a reasonable offensive typing, along with a great utility movepool, but I actually think it's a breath of fresh air for PU. It gives offensive teams an out to almost every form of hazard removal and also the ability to trade against a myriad of offensive and defensive threats with Taunt + Destiny Bond. I actually like how stupidly customisable Froslass actually is, with Will-O-Wisp, Taunt, Spikes, Destiny Bond, Thunder Wave, Disable, and Trick all being viable options on a variety of different sets. Not only do I think offensive Spikes sets will be popular, but I also believe both Choice Specs and Choice Scarf sets could see usage, similar to how Haunter functions. Just because a Pokemon offers a vast amount of support options doesn't inherently make it broken, although maybe I'll be proved wrong.
The final Pokemon that dropped, Scyther is by far the coolest. It was seen as dumb and broken back when it was previously PU back in early Alpha, but right now that's far from the case. With several viable sets and a great speed tier, Scyther will once again shine as a top threat in the PU meta. The most interesting set is certainly the Bulky Swords Dance set, especially with Eviolite + great bulk, alongside Roost making it rather hard to deal with outside of super-effective hits. It is able to set up on a load of defensive and offensive Pokemon, like Qwilfish lacking Thunder Wave, Skuntank, Hitmonchan, Kangaskhan, etc. without the worry of them being able to dent it enough, outside of a critical hit or a potential Defence drop from Skuntank's Crunch. The other main set that will definitely see use is the Choice Scarf variant. Being faster than most of the common Choice Scarf users, like Swanna, Togedemaru, and Primeape will certainly see Scyther shine. Again, another interesting addition to the meta.
I know I wasn't too in-depth with each description, but I just wanted to give my opinion on each drop. Cya all.
Edit: Apparently Quagsire dropped so...
Quagsire is a god-send for stall. The loss of Quagsire forced everyone to fall back on Pyukumuku which, while not a bad Pokemon in any rights, doesn't quite have the same usefulness as Quagsire does. Quagsire is far less passive and able to actually set-up with its Unaware Curse set versus threats like Alolan Dugtrio, without the fear of outright losing to Substitute. Even more balance-oriented teams can use Quagsire, unlike with Pyukumuku, as a useful check to extremely threatening Pokemon such as Aggron (which will certainly rise in usage now that both Gastrodon and Ferroseed have left). Even though I despise stall teams, I'm very excited to see how it functions on balance teams, especially with Gastrodon having left a hole in teambuilding.

+Kris: people think quagsire should have dropped straight from RU to PU because it was PU before it became NU
[00:34]
+Kris: however
[00:34]
+Kris: the only time it was PU was in PU alpha, which does not count
We understand that several of the new introductions may look extremely powerful, and you should expect a council vote on the drops sometime during week. Feel free to use this thread to discuss all things PU meta related, in particular if you have strong opinions on the drops before the council vote happens. That's all, enjoy this brand new tier!
