I am not upset that Kyurem is staying. Given the context of this broken gen of insane offense, Kyurem really isn't that bad. That doesn't necesarrily make it good for the tier. But eh. Everything is just very hyper offensive now. This isn't a broken checks broken argument, either. But the entire gen is broken. At what point do we raise our standards on what is considered broken? Perhaps that has happened with a few mons like Kyurem. It just sucks having to ban like every other mon because it is too much.
To touch on some of the other conversations on here, I do agree that Tera is problematic. I don't know if anything will be done about it. There is a lot of bias for the mechanic. All this has been touched on before. It's just a matter of community will.
If we address rain, I agree that Arch should be the focus. I actually really like Raging Bolt in the tier, particularly since every OU team already runs a ground type. It doesn't take that much more to prep for it, unlike Arch. And we should allow rain to have some bulky options.
If we were to ban Barraskewda, it would just be replaced with some other swift swim sweeper(s). In this gen, literally anything can combine all these bonus multipliers with the Tera multiplier to get insane damage output. The only thing about Barraskewda is, even for a Swift Swim sweeper, the speed tier in rain is a bit outrageous. But that didn't break it before. Anyways, the point is the other potential rain sweepers have much more manageable speed tiers. So if that ever did become a problem, that's about the only way it would make sense to ban just Barry.
Speaking of outrageous speed tiers, did you know D-Speed is actually able to outspeed the entire unboosted tier with only a + speed nature? No EVs even required. The next fastest OU mon is Dragapult, which basically never runs scarf and gets out sped even with 252 EVs and a + nature. This frees you up to put all your EVs in whatever else you want. You could still put EVs in speed to outspeed certain boosted things if you want, but like, you don't even really need to. And your opponent often cannot tell the set and precise speed tier until it is too late.
Yeah, I've tested this thing a bit. While I could use more testing, D-Speed still has me concerned. Not only did figuring out more about what this can do not change my mind on its brokenness, I actually think it's maybe more problematic than I initially thought. The biggest problem is the existence of the mixed Life Orb set. I'm not going to get too into it now, but I have a post coming at some point this week probably. It will take some time to get everything organized.
Now that Kyurem is here for a while, does anyone know a Mon have a switch into it? Or do we not do that anymore?
Although there were some answers given, I think this needs to be touched on more. It's debatable that we really don't do that anymore. Not just for Kyurem but for a lot of mons. The power creep is just so insane this gen.
Even something like Enamorus, which I assume most people wouldn't consider broken at all, is often tough to switch into because of the combination of Fairy and Earth Power. Kyurem has Ice STAB + Earth Power. Same difference. Enamorus even has a physical set it can use with Contrary to catch you by surprise.
Of course, Enamorus is balanced by being a glass cannon. Kyurem has more bulk. But Kyurem also has sub 100 speed. Given the speed tiers of modern gen 9 OU, I believe Kyurem can generally count as a wallbreaker rather than a sweeper. The physical set is a sweeper, but that's more gimmicky and about catching folks off guard.
I havent seen Deoxys on the ladder in like a week i swear
It is currently being overshadowed by things like rain, but I do at least agree with them that at least Speed is fundamentally problematic. Not sure when the player base will realize it.
