Offensively it has quickclaw + quick draw cheese strategies but thats hardly consistent.
Spoken like a lad who hasn't gotten outplayed by a Belly Drum Skillbro that rolled the dice, outsped your +6/+6 Dragapult, and OHKOed it.
Anyway, back to some more VR stuff, I have a few noms to make:
from A+ to S
No matter how the Sword and Shield OU meta evolves, there will always be two constants: Clefable will be extremely good, and Dragapult will find some way to adapt and remain incredibly consistent in the face of an inconsistent meta. Pult is a country mile better than everything except itself and Clefable but Clefable is a country mile better than anything else in this tier. I really do think it deserves a rise to S, though: its usage both in tournament play and on the ladder attest to just how incredibly consistent it is across all levels of play. With Zeraora's best defensive answers trending more than ever nowadays, the one thing that can actually threaten to revenge kill Pult isn't really as much of an issue nowadays.
Whether it's with its flagship Specs set, the DD set that every other HO team runs, or its newer but truly incredible pivot set with Boots, Hex, and either Will-o-Wisp or Thunder Wave, Dragapult will almost always be a threatening presence from team preview onwards. It should most certainly rise; it is clearly a top-tier threat in every way, shape, and form and is a much better mon than everything else, except Clefable. The metagame may have shifted, but Dragapult continues to shift in response, and it'll most certainly continue to do so in the Crown Tundra DLC to boot.
from B+ to A-
Crawdaunt may not appreciate the Amoonguss/Tangrowth spam nowadays, but it certainly isn't a sitting duck against either of them simply because of how hard Knock Off hits the first time, and how hard Crunch (which IMO is definitely the better option currently; CC doesn't hit anything that Crawdaunt's STABs don't already clown on) hits thereafter. Swords Dance Crawdaunt is insanely threatening after a boost and hits for a tremendous amount of damage, while the immediate power of Choice Band ensures that Crawdaunt has virtually zero safe switchins in OU, barring maybe bulkier Primarina variants, and it continues to provide Offensive teams with a very reliable, very consistent anti-Volcarona countermeasure. The lobster is awesome in this meta despite the anti-Zeraora countermeasures that it doesn't really appreciate and should rise a bit as a result.
from A- to A
I know Rhyperior just rose and that this might be a stretch, but Rhyperior is downright phenomenal in this meta and IMO should probably rise even further. I have plenty of experience with the Choice Band set, which has all the tools it needs to devastate anything in the unfortunate predicament of having 178 Speed or less. When Amoonguss started trending a ton, Rhyperior didn't give much of a damn because it just clicks Heat Crash for an easy kill. When Tangrowth started trending, some players started running Megahorn to easily 2HKO it or at least force it into Stone Edge range after a Regenerator heal. When Specially Defensive Tyranitar with Thunder Wave continued its trend of being a legitimately good Rocker, Rhyperior didn't particularly care because TTar is just another target for Rhyperior to either cleanly OHKO with Earthquake or turn into an opportunity to start playing around the switch it would inevitably force.
from C to C+
I don't think it's anything more than a gimmick, but Screens+Belly Drum G-Bro (or, as I prefer to call it,
Skillbro) is a thing that exists, and 44% of the time G-Bro is able to effectively just turn on its Action Replay, blatantly cheat by ignoring its Speed stat, and claim an undeserved kill. I think this set is the only unique thing that G-Bro has to offer at this point (Pex and Amoonguss give it some HEFTY competition as a defensive Poison type with Regenerator), and Grimmsnarl - the thing that enables this absurdly degenerate set - is in C+ as well, so I think G-Bro should at the very least share the same subrank as Grimmsnarl.
from A to A+
I will die on this hill. Rillaboom is Offense's Clefable: it offers so much for Hyper Offense teams that you'd have to be out of your mind to NOT run it. I don't think it's necessarily an S-rank threat anymore, but A+ absolutely reflects how essential it is for its currently-great archetypes (even if HO is a bit inconsistent and as such sees only limited tournament play) as well as how much it actually threatens the current metagame should it opt to run the correct coverage options. Tangrowth and Amoonguss are trending, and while they threaten most Rillaboom variants the Grassy Seed+Acrobatics sets tear past them instead. Rillaboom really doesn't mind these trends too much; it has the tools to adapt, and it continues to do so.
