: This May be Broken after torkoal's ban, but low hp, being outsped by ironball threats, and being weaker to priority, I think this is more healthy, but still a major threat, that will likely be on more teams if Torkoal gets banned.
: Very cool and offensive, fast set up sweeper with regenerator, creating opportunities for switching, and is better than just a dozo check.
: Pretty underused on Ladder imo, either as a belly drum sweeper, or thick fat curse sweeper, are both very strong, but still kept in check with the body pressers and mach punchers of the tier.
: With the only special priority and the very valuable dragon typing, it has favorable match-ups against the big two, and will still have very good use cases if those are banned.
: Both very slow and powerful. I think the physical attacker is more varied, and has a little bit more use, but both are very good wall breakers.
Fastest fully evolved mon and terrain support, could be cool to build around
Strong and not super slow... but still not fast enough to be a mainstay :(
The Punching bag of competitive is now good, and benefits from torkoal's sun, and will probably drop off it is banned
Opposite of Sunflora, I think this will be a metagame destroyer after Dozo gets banned.
Unaware mon that is not as broken, and has more counterplay (maybe this take will age like milk)
Very strong mon, do not sleep on this guy, because after one curse, it can KO pretty much everything
: With How good knock off is, and with how awful 150 base speed is (and with tera being banned), I actually think this will be kept in check.
: If you don't want to ban torkoal, unban this water dragon, origin form is definitely manageable, regular form could be very strong.
: One of the more fun Ubers becomes more manageable when his 130 speed is so bad.
: Similar to Calyrex Shadow, but not quad weak to knock, and a bit faster (but with not as useful ability)
: Again, slow, but very powerful mon worth testing out in the meta.
yea this guy is insane, specs eruption go brr
might be op after a torkoal ban, but for now its ok, gets farmed by a lot imo
im not sure what to think here, tho im leaning ban
curse puts salt into the wound of there being way more slow phys mons then special mons, tho i do want to see how the meta develops with it around
yea this can probs drop, i dont see a world where its op
maybe, could potentially be too strong on tr teams once that implemented (btw it originally wasnt, but it turns out theres a very easy way to do it without making it pet mod like, so as far as im aware it will be implemented soon)
looks incredibly mid, an unban wouldnt shake things up much
would be interesting, but im sane enough to not actually consider dropping it (for now)
So while it may seem obvious why a slow Magic Bounce user would be so good when everything forgoes Heavy-Duty Boots, what really makes Hatt shine is its Speed tier: a mere 29. This allows it to get the jump on almost anything that isn't Torkoal and Clodsire, and with a high Special Attack and good coverage, it excels as a revenge killer + Psychic Noise stallbreaker. Four Attacks might be the go-to set for the whole purpose of a revenge killer, although CM + Draining Kiss still works too. Shadow Ball is great coverage for all the slow Psychic-types in the metagame, although Giga Drain might work too for the physically defensive Water-type foes you can break through. 
Likely the best special wall, Galarian Slowking works as a pivot that is slow enough to outpace a good chunk of enemies with or without Iron Ball. This makes it great as a scout, but also as a Trick user. My favorite set has been the standard Future Sight pivoting set but with Trick + Black Sludge. The extra recovery while having an option to shutdown Curse sweepers and switch-ins like Kingambit makes for a great bonus, plus you can potentially steal the opponent's Iron Ball and get the jump the following turn, like against Torkoal (removing its Sun with Chilly Reception is another nice perk). Otherwise, Iron Ball with another attack like Psychic Noise likely works as well. 
Alomomola basically does the same in OU, but because of its high Speed, it's actually even better as a Wish passer and defensive pivot. Wish Passing is great, especially given partners like Eruption Torkoal, and there's still a ton that it can switch into on and enjoy delayed pivoting. Only a few checks like Sinistcha are actually faster and can punish its Flip Turn. Its passivity is also a concern, as it could be deadweight late-game without something to pivot into and threaten special attackers and Curse sweepers that can deal with Scald burns.
Copperajah is a one dimensional Stealth Rock + 3 attacks user that works in this meta for its base 30 Speed and STAB Sheer Force Iron Head that OHKOes Hatterene. Most teams won't be able to deter it from setting up Stealth Rock, and Copperajah's coverage means that it can be decently punishing with its coverage as well; Torkoal switching into Copperajah may work once, but it may also come at the threat of losing Iron Ball and being swept by Earthquake the following switch in. The prevalence of some counters like Defog Corviknight may limit its potential slightly, but Copperajah always brings something valuable in the offensive support department. 
Despite being very fast, Sinistcha works great as a defensive Calm Mind sweeper that effortlessly counters common foes like Dondozo and Alomomola. It is a great late-game win condition for this reason, but it can still spread status and force out Water-types in the mid-game. The high Speed also means it can afford either Heavy-Duty Boots or Covert Cloak depending on the team. Needless to say, being so fast does mean virtually everything outspeeds it, so revenge killers and stallbreakers are a plenty. 
Even though Clodsire is as slow as Torkoal, Clodsire actually struggles a bit to make a name for itself in this meta. Offensive sets aren't as threatening as its peers, and defensive sets don't do too much more with the speed advantage than what's seen in OU. Still valuable for Water Absorb shutting down Flip Turn, although defensive sets probably will still want to opt for Unaware. 
Yes, Munchlax. Base 5 Speed is that good. Munchlax hits a meager 13 Speed at minimum investment and zero help from Iron Ball, which is faster than Iron Ball Torkoal and, get this, Speed ties -3 Iron Ball Dondozo. So Dondozo can carry Iron Ball and use Curse three times and can still be faster than Eviolite Munchlax. That's why I like to run Encore + three attacks. Munchlax can reliably Encore every Curse sweeper and either follow up to a special attacker. This also makes Munchlax a decent revenge killer, albeit with a passable offensive spread and coverage. The other perk to Munchlax is its ability Thick Fat and huge special bulk, so it's one of the few true counters to Torkoal. What really limits it is the poor Physical bulk; it's a weird fast offensive Chancey for the metagame. 
Magic Guard is a great ability, and so is the coveted 30 Speed tier. Reuniclus can do great with a defensive Double Dance set thanks to the speed advantage and also because of the lack of viable Dark-types to counter Stored Power. Otherwise, an All-Out Attacker set still works great, and its ability offers unique defensive merits over Hatterene, which would otherwise be the more popular option. 
Both of the bros can do most of the same, as both are two base 30 Speed Nasty Plot sweepers at their best. The importance of Nasty Plot shouldn't be understated, as it's not only for sweeping, but also for ensuring the team can break through the slew of Curse sweepers in the metagame. Defeating the likes of Dondozo, Torkoal, and Alomomola is phenomenal. Between the two, Slowking might be better for its unique special bulk, and the spread I suggested allows it to ignore the 2HKO from non-Choice Specs Torkoal's Solar Beam while always OHKOing back at +2 after Stealth Rock. However, Slowbro is much better at countering Dondozo. The coverage of Psychic Noise + Shadow Ball + Grass Knot I believe works best, especially given sun deters Surf usage, and the coverage for revenge killing and sweeping is better than the utility you can get from Slack Off. Of course, there's still room to experiment, and maybe something like Curse + Calm Mind could work? 
The salt titan does much of the same in OU as it does here. The speed advantage is a solid buff, especially because it Speed ties Dondozo. There's also the fact that it counters Torkoal and is a great choice as a Stealth Rock user. There's still the same passivity concerns, although Curse sweeping is a great option even with just Salt Cure as coverage given that most teams won't opt for a Covert Cloak user unless they carry Sinistcha, which already would be a counter with or without the item. 
In most regards, Hisuian Samurott took a huge nerf with its high Speed, yet still was able to make a dent with Ceaseless Edge being the bane to Iron Ball spam teams. Hisuian Samurott is also a decent user of Encore and Covert Cloak to check Garganacl, although its harder to get off multiple hits with its high Speed. 
The speed flip is, in almost all regards, a huge negative to Kingambit, as most physical walls are guaranteed to outspeed it as long as they run Iron Ball. This in turn discourages Iron Ball usage from Kingambit, so expect the usual fair of items like Black Glasses, Air Baloon, Leftovers, and Lum Berry instead. The metagame is in dire need of priority sweepers, so Kingambit still fulfills this niche and does well enough in some matchups, like dealing with the Pyschic-type infestation. 
Even though the speed flip makes Corviknight a guaranteed slow pivot, not much else has changed. It's still the dedicated Defogger for most teams, especially stall. It also has passivity issues, and Curse or Iron Defense sets are underperforming from what I've seen. 
There's a small niche in having the combination of Sturdy, Stealth Rock / Spikes, Taunt, and Hammer Arm at such a low Speed of base 30. Sudowoodo can be hard to switch into thanks to STAB Head Smash, which also ensures Rapid Spin Torkoal may not remove its Stealth Rock if hit by Earth Power, making it an effective lead even if it cannot totally deal with Hatterene by itself. 
Alolan Muk works on stall for being a Dark-type that spreads status and dealing with Psychic-types.
Stall. It still works. 
Sweeping with Hammer Arm and Ice Hammer works well enough for the added Speed drop. Conkeldurr can be a decent stallbreaker with Taunt, whereas the slower Crabominable hits the more favorable for sweeping given it hits 27 Speed at -1 and with Iron Ball, which is one point slower than Iron Ball Hatterene. 
Its typing and good bulk makes it an anti-meta Nasty Plot wallbreaker, even if it is on the faster side. 
Wow is this thing strong. The poor Speed tier is a solid nerf, though.

This guy is a bit of a later pick that will probably be more viable after certain mons get banned... 
Despite it's "high" speed, Glimmora has shown a surprising bit of utility for me as a janky semi-lead mon. Slow Mortal Spin is actually quite useful if your opponent is trying to set up hazards, and Glimmora also has access to Reflect/Light Screen, which, while ethically questionable, still is pretty damn good. Hazards are obviously really good in this tier - nobody's running boots, because you pretty much HAVE to run a slowdown item, barring certain nonspecific instances. With that being said, Glimmora is obviously a premiere hazard setter, and should at least be considered for Hazard Setting/HO teams.
