I just wanna talk about a couple of meta trends that somehow haven't really been addressed in this thread yet.



You have certainly had many dealings with these four if you've been playing in or watching tournaments recently. Gliscor balance has become the unquestionable defining playstyle of the metagame, mostly on the back of the Spikes+Protect+Toxic set. Arguably the single best progress maker in the entire tier, this thing sticks around forever unless you have a way to severely damage or outright KO it while also preventing it from Spiking
or statusing whatever your current Pokemon is. This is, shockingly, incredibly challenging for a lot of teams to confidently do, especially when paired with the above teammates. GliscPex has become one of the defining cores of the tier. We all know what these two can do defensively at this point, and breaking them is extremely challenging even if you have a theoretically ok matchup because Gliscor is littering the field with Spikes and both of them can spread status to wear down your breaker extremely quickly. Great Tusk
should be threatening to these two on paper, except it can't confidently switch in at all and has to choose between the correct coverage move to hit Gliscor or Toxapex as well as the potential to Rapid Spin to clear the Spikes (or Stealth Rock but Spikes Gliscor is usually run these days) that are chipping down its team. That is, of course, not to mention the fact that these teams often have additional insurance to strong physical breakers. You have to do a happy little dance that involves perfect prediction with your wallbreaker as well as not taking any status condition
or hazard damage because GliscPex will outlast you. Ferrothorn and Gholdengo complement this core well by helping sponge dangerous Psychic- and Fairy-types while also having notable utility themselves. Ferrothorn can add up the residual damage even further and create a deadly hazard stacking core with Gliscor. This thing had an insane run in Blind Draft, just check out the usage stats alongside the winrate. I don't think a single other Pokemon came close to that success in OU. Ghold is pretty self explanatory at this point. It can help maintain hazards and exerts significant pressure itself, not to mention how its the single best and most splashable Tapu Lele check in the entire tier. If your team cannot break these balances it is simply not a good team in the current environment. It's a big reason why things like Kyurem, Volcanion, Nidoking, and other fringier balance breakers are worth considering in serious games. However, there are other ways to break these teams open, for example...

One of the best ways to pressure the balance teams above is through FuturePort offense. I talked at length about these two, and why I think they should rise, in a VR post I made recently, so check that out if you want specifics. The extremely slow pivoting is also crucial to their function, however, as switching into the above balance core is very challenging for many offensive Pokemon, and these two take a ton of pressure off. Slowbro in particular can sponge a Toxic from Gliscor or Toxapex if it absolutely has to, and its oftentimes worth the effort if you use that opportunity to position yourself to take down a piece of the above core. I particularly like pairing these two with Urshifu-RS and Mega Lopunny. Urshifu doesn't care about Gliscor's Protect shenanigans at all and loves being able to freely click its STAB moves without Toxapex getting in the way. Meanwhile, Mega Lopunny offers a ton of additional utility in terms of shoring up the offense matchup, and it restricts your opponents ability to try and pivot around the incoming STAB move with Gholdengo. Boots Zamazenta is also a nice choice for this role, as it also adds speed control alongside excellent coverage and Stone Edge to deal with birds that may come to play in other matchups. This can really work with a bunch of different breakers though, so pick what works best for your team and go wild. I firmly believe that FuturePort is one of the best offensive playstyles available right now, as it can slice through these balances with proper play and can generally exert a ton of pressure in most matchups.
I'm not advocating for any imminent tiering action, but Waterpon is by far the most broken offensive threat in the tier in my opinion, and I'm a bit baffled as to why I don't see more of it. You would be hardpressed to find a better offensive progress maker in the current metagame, and our defensive options are simply terrified of the simple Swords Dance set. Water/Grass has amazing neutral coverage right now, and the choice between Superpower and Play Rough can be made depending on what your team most needs cleared out of the way. Depending on the coverage move, your best options are either Ferrothorn and a couple other extremely bulky Steel-types, or Dragons like Mega Latios and Dragonite. The list of surefire defensive answers are mostly restricted to very fat Grass-types, none of which are particularly easy or satisfying to fit on teams, with the possible exception of Mega Venusaur, as well as Multiscale Dragonite, but with good prediction and a bit of support you can find ways past all of these. You have to play extremely carefully around a well supported Ogerpon, as it can cleave through teams at a moments notice with just a little bit of hazard support, or chip on your Dragon or Melmetal, or just an opportune Ivy Cudgel Crit. A lot of teams simply tried to revenge kill it as recently as early in Blind Draft, but this is a very iffy strategy, especially since the meta is trending fat, again, and a lot of Waterpon revenge killers do not match up particularly well into the bulkier metagame, not to mention that actually OHKOing the thing isn't easy either thanks to its good typing and not-insignificant bulk. This is further compounded by Dragapult leaving, which I generally supported but it was one of the best offensive checks to Waterpon, as it could both burn it and maintain momentum for its team. Again, I want to see how the metagame continues to develop post Pult, but I do believe that this will end up needing tiering attention.
The pivot set is bad stop running it.
