I bowed out from contributing to the initial rankings because I was busy and hadn't played enough to feel like I should offer my opinion, but after playing a good amount I'd like to add my thoughts.

I think Doublade is really not that great. I'm not gonna detail you on all of its faults, but I really think the metagame is just too unkind to it. Everything is pretty much set around so that it can handle Doublade just fine. It's very easy to have surefire counterplay against; Sirfetch'd is as good as it can get offensively, Haze Milotic is pretty much the best defensive check, lots of good bulky Grounds get in the way of it really easily, and a multitude of really good checks the tier has to offer, such as Mamoswine, Diggersby, and Umbreon. Its speed is obviously its biggest flaw, making it incredibly susceptible to things like Umbreon, Vaporeon, and even preventing it from even threatening Galarian Weezing, as Feliburn touched upon earlier. It really almost never sweeps unless you face something truly atrocious. Its defensive utility is solid, but lack of recovery is really so killer and Wish support is not an adequate remedy to that. Defensively, it offers a lot. It's a viable Steel-types in the metagame, which is huge with how few there are. Its typing is incredible for defensive purposes, and it is most definitely an incredible offensive glue. I think S is very much so overselling it, and believe it should drop.

I thought people were overhyping it a tad before I really got into playing the post big goons meta (Crawdaunt / Gengar / Obstagoon), but I was wrong. Milotic is honestly just so good, its bulk is so incredible, so few Pokemon have access to Toxic that the fact Refresh got nuked is near meaningless at the moment, Grass-types not named Roserade are pretty niche, Scald is bonkers, etc... It's just really good. I've even seen it Scald Umbreon to trigger Marvel Scald, thus allowing it to wall things like Diggersby, Lucario, and Mamoswine, which is pretty wild and hilariously effective. Milotic is also, sillily enough, one of the most reliable means of beating Noivern. Noivern is honestly pretty annoying in a vacuum considering its movepool, so having a bulky Pokemon with Ice Beam is extremely clutch. I don't think Juuno's take is actually that crazy anymore, I feel Milotic is most certainly A+ material, and if Doublade isn't S, I'm not really sure what would be and would be a league above Milotic. Not saying it should be, but I think it's a pretty fair stance. A is really underselling it right now.

Tying into the Milotic discussion, Roserade is pristine right now. It's the best offensive Milotic check possible, it's really annoying to switch into, and it also has access to Spikes. Yeah, no Hidden Power kinda blows, but in this metagame you wouldn't really run it in the first place. Synthesis / Spikes / Sludge Bomb / Giga Drain @ Life Orb is all you need. Obviously it has its issues, like somehow its a special attacker that lets Durant in for free (??) as well as the fact its physical bulk is quite abysmal. There are a lot of ways to handle it, but I feel Spikes are super good and it's a really good Spike setter, on top of the fact it's the best way to beat Milotic without using either one of a) sac mon then bring in offensive mon b) pray i don't get scald burned or c) reactionary defensive switchins. I think it should rise.

Diggersby I feel is being undersold in A. I think it's on par with Mamoswine, but the two offer a lot of different tools to a team. I'm not going to get into "Well, you, see Diggersby is actually stronger than Mamoswine, thanks to its ability, Huge Power, which doubles its Attack stat..." BUT Diggersby is really strong, and I feel people are sleeping on it. Compared to Mamoswine, it learns SD which can be huge, coupled with its already great power + priority quick attack, it can also run Agility which is more niche but still can be potent, but the thing I like the most about it is its Scarf set. Scarf Diggersby has been absolutely killer in my time laddering the past week or so. While, obviously, a lot of teams have both a Ground immune and a Ghost-type, thus neutralizing its STABs, they are still not safe switchins, and during the course of a game, Scarf Diggersby can be a very potent cleaner. I've found many instances where it ends up cleaning with either Body Slam or EQ. Its filler move also offers a ton of utility; Ice Punch or Spikes. Ice Punch nets the OHKO vs Noivern, which can be huge (I can't say how many times Noivern has switched into Diggersby while laddering + my own got sniped by one), while Spikes.. well are Spikes. I didn't click it many times while laddering but when I did I won the game off of the fact I had it. Spikes are super cool because getting them up vs bulkier builds or later on in the game to help Diggersby clean itself is really sick. I think this Mon is A+ material.

Reuniclus just seemed way better in the post big goons meta; two big Dark-types with Knock Off gone. But still, Reuniclus isn't A+ material I think. It is one of the few Pokemon that can actually shrug off Milotic burns with ease, but you have to run more awkward sets to beat Milotic in the first place thanks to Haze. The metagame is not very kind to it; the strong Pokemon are REALLY strong. Mamoswine, Diggersby, Chandelure, Haxorus, and Durant all pummel it even if it gets the opportunity to CM up. Not to mention Doublade and Umbreon. A+ is a bit of a stretch I think.

man Specs Gardevoir is SO GOOD. This tier is sooo lacking in good Fairy-type resists, most teams only use Weezing, Doublade, or Chandelure, when that really is not enough, although there really aren't any good options for it in the first place. Specs is actually absurdly strong, it's the most fun mon to use for me. I imagine Scarf is pretty solid, because I feel there aren't too many good Scarf options, but yeah, use Specs. This Pokemon is definitely A material.

IP was right: CB Bronzong is kinda good. Much like in OU, with a lack of Z Moves and Mega evolutions, Trick is incredibly underrated and under-explored in my opinion. I've been using Trick CB Bronzong with SR and a defensive spread to much success. Can also run Toxic Orb or another item. Its typing + Levitate is incredible in this metagame, with Diggersby and Mamoswine running rampant. Lack of Toxic isn't even a big deal with Trick in my opinion, and the defensive utility it offers is great. Really though, Trick is good, more people should try it on other more things. Bronzong should rise though, it's not that bad.

Hustle sucks.

Really not that good. It's super annoying in the teambuilder, but I don't think it's the only Pokemon that makes UU restricting like it is or require Dark-types. B+ is more fitting.

What do these do over the alternatives? Like, what does Sigilyph do that either Gardevoir or Reuniclus don't? I know the speed but it struggles with Umbreon way more than the other two and is way weaker. Once it gets Defog sure. Pangoro I'm not sure why you'd use it over Sirfetch'd, or even Bewear I guess. I feel both these mons are little too highly ranked.

should drop

should rise
too early to rank Galarian Corsola or Dracozolt but I don't think either will make a huge impact on the rankings. Maybe Corsola lowers Lucario and the non-Sirfetch'd fighters. Maybe Dracozolt makes Pyukumuku worse when you could be using Quagsire. Who knows.
