There's been a lot of talk, either in terms of potential suspect tests or in a more general sense, about Magearna and Cinderace. They're both obviously very top-tier mons and the undisputed two best mons in the tier (though which is the best or the second-best is admittedly more up in the air), but I feel like there are some other mons that, though accepted to be great for some time now, deserve to be talked about now more than ever. They aren't broken, but they're all certainly excellent.
Landorus-Therian has been on a truly meteoric rise back to stardom as of recently. It continues to do the things Landorus-T has always been good at; that is to say, it can do basically anything you want it to do, but cannot do everything you would want it to do. It's a good Choice Scarfer in a tier devoid of good Choice Scarfers, it's an excellent pivot and Rocker, and it continues to find its way onto almost any team archetype due to the absurd amount of role compression it offers. And at the end of the day, it's still Landorus-T through-and-through: it's excellent at almost anything it does, but it's never overbearing and always honest. Magearna and Cinderace are both obviously the head honchos of OU, but I think Lando-T has solidified itself as the undisputed third-best mon in the OU tier.
I've thought extremely highly of
Garchomp since the very beginning of the Crown Tundra/DLC2 meta--I even went so far as to put it in the S-ranks on my personal VR in a meta still occupied by the likes of Zygarde, Kyurem-B, Pheromosa, Urshifu-S, and Spectrier--but in a much more developed DLC2 OU metagame Chomp has truly taken off. Back then I thought very highly of Tank Chomp, and while I still think highly of it I firmly believe its Swords Dance+Scale Shot set is one of the most definitive OU threats. Yet despite being an absolute beast offensively with its nigh-untouchable dual STABs and great coverage alongside its ever-important 102 Speed, Chomp is never a slouch defensively either. It's still able to reliably set up Stealth Rock and it still offers teams with all the excellent qualities of a fast, hard-hitting Ground type that is mandatory on nearly any team. Physical attackers, and especially U-Turn/Flip Turn users, detest its existence thanks to Rough Skin.
Garchomp is considered to be arguably the fourth-best mon in the metagame, behind Magearna, Cinderace, and Landorus-T, but I think that it and Landorus-T have never been closer to equal than they are now. It's just as splashable and it's just as consistent as its Ground-type comrade-in-arms, but it succeeds in manners Landorus-T cannot, and vise-versa. These two completely and unconditionally define what it means to be a Ground-type in OverUsed currently; you will almost
always be building a non-Stall team with one of these two in mind. You can often modify a team with Garchomp slightly and substitute Landorus-T for it, and you can often modify a team with Landorus-T slightly and substitute Garchomp for it. Garchomp and Landorus-T are the platinum standard for Ground-types; any Ground-type you would
ever consider running in this meta must first differentiate itself from a member of this duo; all Ground-types that fail to stand out will remain in their shadow. Fortunately, though, there are some Ground-types that absolutely manage to stand out in a world where these two set the bar so incredibly high.
Galarian Slowking has been one of the most defining mons in OU for quite some time, and after the ban of one of the few special attackers that could reliably beat it 1v1 this thing is slated to become, in my opinion, one of the ten best OU mons. This thing is so absurdly good at what it does that I firmly believe it's singlehandedly keeping Magearna honest. It blanks almost every Special Attacker in the tier with its flagship Assault Vest set and is basically impossible to switch in against except with one's own Galarian Slowking, but I've been experimenting a great deal with the Nasty Plot set that recently came up in this thread and it is an absolute behemoth in its own right, leveraging the King's incredible typing and movepool to break past defensive threats it has no business breaking past. I often find myself just slapping either Assault Vest or Nasty Plot Galarian Slowking on a team and just making it automatically better; it's that good.
Going back to its Assault Vest set, usually walls are a bit more on the passive side; this couldn't be further from the truth for the King, though, as he has virtually no safe switchins. Nothing that can eat a Sludge Bomb appreciates either getting Poisoned or eating a hit from its bottomless movepool. It has Earthquake for both Heatran and the incredibly common Slowking mirror; it has Ice Beam for Chomp and Lando; it has Scald or Hydro Pump for most Grounds and most Fire-types; it has Icy Wind for additional utility; this thing has everything going for it and then some, and the only issue is deciding what that final moveslot is supposed to lure in and defeat; its STABs and Fire coverage do enough work on their own.
Hydreigon's defensive set--the set that saw the most prominence in the Spectrier meta--is now dead. But instead of its only niche being eliminated, the only reason why that set was mandatory has been eliminated instead, which gives the hydra the ability to once more spread its wings and run its absurdly dangerous offensive variants. Nasty Plot Hydreigon has almost no defensive counterplay once it gets going, as long as it packs the necessary coverage, and it has the longevity to ensure that it can come in multiple times a game and wreak havoc. Hydreigon's defensive utility still exists, but now it doesn't have to play exclusively towards its defensiveness. Hydreigon has a lot of potential to become a
big part of the meta once again.
Yet another mon on a truly meteoric rise,
Tornadus-Therian is extremely consistent as a pivot, as a Defogger, and as a breaker thanks to its newfound access to Nasty Plot. It is without question the best Defogger in the tier, and with moves like Knock Off and U-Turn in the support department and its powerful Hurricane and incredible coverage in Focus Blast and Heat Wave, Torn-T ensures that it can always threaten basically anything in the OU tier, so long as Hurricane and Focus Blast connect. Regenerator was expected to run the OU tier this gen, and with this thing, Slowbro, and Galarian Slowking becoming better than ever that reality suddenly doesn't seem so far-fetched.
Dragapult took a surprising nosedive in terms of both ladder usage and overall ranking on the VR, but started returning to the limelight come SPL (even when Spectrier was still around). Spectrier's existence did Dragapult few favors, though; while Dragapult has the Speed to outpace base 130s quite easily with a +Speed nature, it often had to forego significant power to do so in order to not become yet another Spectrier victim. Now that Spectrier is banned, Dragapult can keep doing all the things it's good at--pivoting, spreading status, wallbreaking, revenge killing, setting up for a sweep, and the like--without foregoing any of its power to do so since it can now afford to run a neutral nature. Whether or not Dragapult will once again become one of OU's absolute top threats remains to be seen, but the metagame's recent changes are certainly setting up for Dragapult to recapture at least a semblance of its former glory.
Kyurem is yet another rising star in the meta, and not too many people should be particularly surprised by this fact. There is absolutely nothing in OU that can safely switch in against an unscouted Kyurem, and more players are exploring its set diversity on the ladder nowadays. Of course, Specs is still the one set that instills fear in many; the chill that runs down an unprepared player's spine as he or she stares down a Specs Kyurem that comes in safely pales in comparison to the chill that will run through the defensive backbone of a team that, most of the time, isn't prepared to switch in on a Specs-boosted Ice Beam or Freeze-Dry. But Sub+Roost, Dragon Dance, and Sub+DD are still very threatening, and while Specs is often a candidate for OU's new best wallbreaker the threat of the unknown is often even bigger than the threat of Specs; it can very realistically muscle past its checks with a different set, and it's up to you--the player staring at it in Team Preview--to figure out how to figure it out and stop it first.
The post-Spectrier meta has a lot of potential to be very interesting, and I'm quite interested in seeing how these threats will perform both on the ladder and in tournament play going forward. What do you all make of them?
