A response for the survey, because sure, why not.
Ban, please. I'd say it's currently the most dangerous threat in the meta, with its sheer versatility and staying power. Combined with thousand arrows, it has a set that can beat almost anything. Choice band can take care of some faster threats with extreme speed and Clefable with iron tail, sub coil/ddance sets up on too many things to be easily stopped without potentially risking choice band, resttalk is annoying as hell, there's some thousand waves sets that can take out some of the more annoying things for it... and that's not even mentioning glare, which is probably what pushes it over the top, ensuring that nothing could possibly reliably check it with that 25% chance to just not move. And it also gets toxic, to boot, for some things that might not care about glare as much, or that might otherwise not take that much damage from it. I guess Fini checks it pretty well, compared to other options? Rillaboom is usually okay against it too, if it switches in early enough (although Zygarde loves the passive recovery of grassy terrain). But there's not a whole lotta consistent answers, and the situational ones just get blown away by the wrong set or parahax. Very unhealthy, very centralizing. Ban it.
Another ban. Not quite as big of a problem as Zygarde, in my opinion, but dragon dance and icicle spear push it way over the edge. After just one dragon dance, it can reliably defeat anything not named Melmetal, depending on the set. Sub allows it to abuse anything that might want to status or outspeed it, roost keeps it healthy longterm against most priority, and dual wingbeat allows it to decimate Buzzwole, which is otherwise an admittedly good answer. I know icicle spear is inconsistent, but it does have a notable benefit of hitting multiple times, meaning some things that could've killed it under a substitute like some variants of Zygarde aren't reliable anymore. And fusion bolt, as everyone knows, rounds out its boltbeam coverage to let it decimate water types that might otherwise check it, like Toxapex and Fini. Ban it. Please.
It's fine, for now. Hard hitting, hard to kill on the physical side, and double iron bash pairs well with trick room for bullshit flinch hax stuff, but it's outsped by almost literally everything, and is very vulnerable to chip from hazards, rocky helmet, rough skin/iron barbs, and voltturn. Its special defense is shit, so any moderately strong special attacker threatens it out unless it has assault vest, in which case it kills a lot less things than it does with choice band. I think it might warrant a closer look after the biggest threats are banned, but for now I think it's perfectly balanced, albeit definitely a top threat.
I think this deserves a suspect after the quickbans are done, but shouldn't be quickbanned. It's not overwhelming, currently, but it is very very annoying. It does have 4MSS, but it can bypass all of its checks with the right set--throat chop for ghost types, drill run for Toxapex, and triple axel/ice beam for flying types/bulky grounds like Zygarde, Landorus-T, or potentially Garchomp. However, if it lacks that coverage the mons in question don't really care about anything it can do to them, and no matter what it struggles with some consistent answers--mainly Zapdos and Moltres, which have a chance to paralyze or burn it, respectively; Moltres in particular is good against it, since it laughs at stabs and mostly shrugs off triple axel or ice beam. So yeah, although it's very good, it is inherently limited and has some pretty solid checks that are on most teams, so I don't think it's broken yet. Good to look into after other things though, and see how the metagame changes inevitably effect it.
Not broken at all, currently. It's good, but its bulk and typing is defensively atrocious, for the most part, especially with life orb. It also gets hard checked by some things, like FIni (it's good, use it more). It's a little strapped for moves; it wants thunder punch to deal with some of the birds, but earthquake is better against Toxapex and some other things. It wants swords dance to break through some of the bulkier stuff, but it also wants protect to guarantee a speed boost or two, since its initial speed isn't that great. There are some cool options you can use, liked mixed Blaziken with fire blast/earthquake/close combat/protect to nab Lando-T on the switch (I forget who came up with this but whoever did, thank you, it's fun as hell) but it's not overly viable in the long term. As such, I think it's perfectly balanced. Good for offensive teams, fits well on sun, does well against some defensive backbones and some forms of offense, but overall not overbearing in the slightest.
Not broken. It's threatening, it's versatile, and nasty plot makes it a top tier threat, but it's very frail, meaning a lot of priority can easily take it out. There's also a lot of speed control running around for Regieleki, and most of them can take care of Tornadus-T pretty well. And, despite regenerator, it's not that great at staying alive while keeping itself a menace offensively; heavy duty boots means that it lacks initial power, while life orb means that it takes stealth rock damage and gets worn down real fast. Great mon overall with both offensive and utility options, but not broken currently.
Annoying as hell, but not broken. It has no coverage outside of dark pulse (lame) and mud shot (bad). It's good, don't get me wrong--it can spiral out of control real fast if your answer to it is hindered or dead, and the wisp+hex+sub set is pretty nasty. Not to mention that it can pull of disable shenanigans if you so choose. However, getting hard walled by every single relevant normal type and dark type sucks horribly for it, so it's not broken, just a bit irritating. Shouldn't be banned.
This is a weird one. As of right now I think it feels maybe not broken, but I think that's primarily because there's a lot of things in the tier that kind of just murder it that might be gone sooner or later. The main one is, of course, Zygarde, which outspeeds and threatens with thousand arrows. It's also in a different metagame outside of Zygarde than DLC1, where Garchomp and Lando-T also threaten it with strong ground moves, while Blaziken and assault vest Melmetal also work pretty well against it (assuming it's not set up already). At the same time, it's just so damn versatile, with basically infinite ways to set up and customize itself to abuse specific answers to it, and it has great bulk that allow it to take a hit or two to set up a shift gear, calm mind, or what have you. And on top of that, there's the infamous specs set, which still just wrecks shit. So I dunno. It definitely deserves a suspect after Zygarde and the like are banned, but I'm not quite sure if it's quickban material.
Excellent but balanced in this current metagame, I feel. It was broken before, but a lot of new things have popped up to give it a headache--bulky grounds, Zapdos and Moltres, and faster mons. It feels like it doesn't have the coverage to effectively deal with everything it wants, and it's still susceptible to being worn down by weather, priority, or by hazards if choice band. Sucker punch does alleviate some of the speed woes, but it's not enough to make it broken. Probably deserves a look in whatever the next metagame after bans looks like, but as of right now it's just dang good.
Not broken at all currently. All of the offensive options running around, like the new grounds, Regieleki, and Kyu-B, are making its job of never dying pretty difficult, under the right circumstance. However, some of those offensive options, like Zygarde and Kyu-B, might end up leaving, so it might be worth looking into then, as two major things that kill it pretty easily will poof out of existence, freeing it up to do its job a lot more effectively. And to be fair, it's still pretty damn unkillable despite the new threats, and it handles some of the new mons like (some) Blaziken pretty well.
Do not unban this, ever. Or suspect test it, ever. It would be broken as hell regardless of what bans took place first. It's fast, it's strong, it's surprisingly bulky, and it can hold an item. It has a spammable stab move and decent enough coverage, and overall is just way too good for OU. Please don't entertain anyone who says it deserves a suspect. It doesn't.
This one is more interesting to me. The main issue it has is the inability to hold an item; this severely limits any offensive potential, which sucks when it's primarily an offensive mon. No recovery hurts it a lot, meaning that as a wall it can be easily worn down, howl sucks for the only setup move, and although the steel typing is largely a good thing, it does have some drawbacks against the ground types that have been added. At the same time, it's very bulky (especially with the automatic +1 in defense), it's pretty strong with two good stab options (close combat and behemoth blade; although spamming steel moves isn't always the best idea, it's high BP means it's probably going to be pretty decent against most non-resists), it's pretty dang fast, and although howl sucks for setup, it
is still a setup move. I'm not sure if it would be broken or unhealthy if reintroduced or not, which means it probably warrants a suspect test. However, I think that any suspect of Zamazenta-C should come AFTER all quickbans and suspects for broken mons are completed, so we're not stuck in a potential broken checks broken mindset. ("Kyu-B can't be broken, Zamazenta-C can switch in, outspeed, and kill it!" is the kind of sentiment I want to avoid.) But yes, a suspect down the line may be warranted.
Those are my thoughts. Thanks for reading, and all that
