What have people been thinking about Gliscor in the metagame? There has been some chatter in tiering circles about Swords Dance variants. I do not find pivot and Spikes sets to be problematic in the slightest right now, but we have gotten some complaints about SD / Facade / Knock / Protect.
I am not sold on it being broken personally as I find it possible to pressure, but there are some archetypes it pressures well and some limitations on team construction for sure. It is a big part of my job to both do due diligence and hear a wide range of perspectives, too, so would love to hear where people are at.
While I don't feel like Gliscor is broken offensively per se, I think that what it does to the tier may be considered unhealthy and warrants a suspect. It's not that the SD sets are un-wallable, its that they contain a devastating combination of damage output, bulk, its typing, and continuous healing. It's been said many times before, but this combination of traits, in tandem with its typing and the ability to tera, means that Gliscor can almost entirely invalidate certain playstyles and team structures, particularly bulkier builds. Indeed, all Gliscor sets can be beaten by well constructed hyper-offense and offense teams, but the fact that Gliscor has the ability to invalidate entire playstyles makes it arguably broken or worthy of another suspect at the very least. If you build a balance team, you pretty much NEED to have some sort of fast encore, a strong offensive ice or water type (which are rarely run on balance other than Weavile or Samurott), or an IDef Corv or else you can just lose to an SD Gliscor at preview. Yes, metas change and it's not that all playstyles have to be equally viable, but to have certain playstyles be completely unviable seems unhealthy for a metagame (it's worth noting that Gliscor is not the only reason why balance is struggling so much, but it is arguably its biggest roadblock).
It is also clear that the SD sets are the most dangerous and unhealthy sets that Gliscor runs. Defensive sets are very annoying, but they can typically be slowly handled even by balance teams, so long as they are well-constructed. For example, defensive Gliscor cannot touch any Corviknight, allowing you to easily pivot on it, and it also loses to SD Gliscor in return. It is precisely the fact that Gliscor is so bulky and has automatic chip healing while simultaneously being able to output such offensive pressure which makes Gliscor such a menace.
There are also some implied but not-as-often vocalized aspects to Gliscor that make it so potent, especially against balance, that I would like to mention. I think these points are best for people questioning what makes Gliscor so strong:
1) Hazard indifference: It is immune to spikes and shrugs off rocks damage. This just allows it to enter the field so easily without worrying about hazards whatsoever.
2) Limitless tera options: Not only is its base typing already one of the best in the game, meaning that it doesn't even need to tera to be so dangerous, but it does appreciate tera, whether it be to flip a matchup, become just an overall solid defensive type, or to boost its damage. I have seen Normal, Water, Fairy, Dragon, Ghost, Dark, Steel, and even Grass teras on the ladder, and I honestly cannot say that any of them are necessarily bad options. This myriad of possible typings only makes it harder to predict and deal with.
3) Knock Off absorber: It is arguably the best Knock Off absorber in the game, perhaps second to only Clefable. This is just an amazing trait that allows Gliscor to switch into an oncoming Knock Off and not mind losing its item at all (assuming it's already been poisoned, of course). Once again, Gliscor is incredibly easy to get onto the field and do what it does.
4) Status immunity: you can't even use status to cripple it, and hex bounces off of this thing (unless it is NP+Ghold or Specs Hex Dragapult, but both of those lose to tera normal)
5) Knock Off user: Gliscor is also one of the best Knock Off users in the game. Not only does it pair so well with Facade because it can hit ghosts, but Knock Off on Gliscor is so perfect because it doesn't mind trading Knock Offs with the opponent and because of the way that hazard stack works, the team structure that SD Gliscor probably works best on. Hazard stack teams are most effective when they don't mind hazards going up on their own side of the field either, and this is typically remedied by have boots-spam. Not only does Gliscor easily Knock Off the opposing mons' items, allowing its teammates hazard stack to become more effective, but it also doesn't mind getting knocked off at all either, as discussed above. This means that against an opposing hazard stack or balance team, Gliscor can always come in on an incoming Knock Off trying to remove a teammates' boots before using its own Knock Off to an asymmetric effect, given the fact that you are pairing your Gliscor with hazards (It's funny, it often feels like the only real way to beat a Gliscor is with your own Gliscor).
Although this post seems like I am adamantly against Gliscor's presence in the tier, I am still on the fence regarding a ban or not, and think that another suspect is due. I have alternative reasons why I don't think that Gliscor is banworthy, including but not limited to the fact that Gliscor is ultimately not an un-wallable machine that can win any given match like some other banned mons are
