I've been playing a lot of OU over the past couple of days. It's pretty fun, but the tier is absolutely broken and madness.
I would like to start off by sharing an offense team that I've been having a lot of fun with!
(click here)
This is a pretty typical offensive team built around Kyurem-B, which is a very potent wincondition right now, though I am not convinced it deserves to be quickbanned in the first wave. It has a number of flaws that I will get to later in this post. Choice Band Genesect is honestly one of the strongest Pokemon around right now; it holds some great natural defensive utility thanks to its Steel-typing, being a fine pivot into Pokemon like Tapu Lele. Beyond that, it also offers one of the best forms of Speed control in Extreme Speed. Priority in general is really key to this metagame, as it is ridiculously hard to not fall behind Pokemon like Naganadel, Pheromosa, Blaziken, and Kyurem-B without it. Tapu Koko is really useful because of its defensive typing and the Speed control that it provides. Tornadus-T is absolutely one of the biggest threats to offensive teams like this and having Tapu Koko to stop it from easily breaking the team down is really useful. Beyond just that, not a lot of Urshifu-S have been running Poison Jab due to the absence of Clefable from the meta, so Tapu Koko is a viable pivot into it, though keeping up momentum to limit Urshifu-S's opportunity as much as possible is definitely more desirable.
With the addition of Tapu Koko, Regieleki, and Volt Switch users in general being as prominent as always, I cannot stress enough how important it is to have a Ground-type. Landorus is pretty ideal for this slot; it is a Ground-type, one of the best wallbreakers in the metagame, and it can set Stealth Rock, which it is very good at thanks to its ability to pressure Defoggers. I've been opting to use Sludge Wave in order to pressure Latios, Latias, and Moltres, but Psychic is a very viable option to hit opposing Landorus. In general, I don't think Latias is great, but it works wonders for teams like this. I was originally set on using something like Focus Sash Alakazam here, but Latias is one of the few viable stopgaps to Landorus and Blaziken, and it can also pivot into some sweepers like Zygarde directly. Beyond that, it's one of the best Pokemon to compress Defog onto, and Healing Wish is really good on this team, being able to provide Kyurem-B, Genesect, Landorus, and Urshifu all with a second chance, so you can be a little lax with HP management.
Lastly, I have found Urshifu-S to be a really potent wallbreaker right now with the lack of Clefable to check it, allowing it to run U-turn + Sucker Punch. Not just that, but Urshifu-S also brings some notable utility to the table as a Ghost resist. With the addition of Spectrier and Dragapult still being as good as ever, having a Ghost-resistant Pokemon available that can pivot in atleast once is really important. Unfortunately it does struggle switching into Will-O-Wisp, but I have not found this to be too big of an issue thanks to Healing Wish. Sucker Punch in general is really great to bail you out against some Pokemon like Naganadel, Pheromosa, and Kartana as it often happens that Genesect is not quite enough for these Pokemon. Having Urshifu-S as the dedicated Ghost resist is obviously not ideal, but considering how well this team forces progress, it has been working out quite well for me.
I know the above is a lot to read about for just one team, but I wanted to fully cover my thought process behind it. I'd be interested to see how other people are going about teambuilding right now too!
I'd also like to share my thoughts on some of the new Pokemon.
Genesect is, in my opinion, very clearly the most broken Pokemon right now. It is ridiculously versatile, with sets like Choice Band, Douse Drive, Shift Gear, and mixed all being very strong in their own right. You don't really know what to expect from Genesect at any point thanks to its versatile movepool and good stats to back said movepool up. In general it's pretty hard to use Genesect checks like Heatran and Toxapex due to the pacing of the metagame really limiting what they can do, but counterplay does ofcourse exist. Every set has its own set of problems, but together they make for a ridiculously difficult Pokemon to keep in check.
Landorus has its share of offensive counterplay; its Speed tier is pretty mediocre and its bulk, while still respectable, does not allow it to survive hits from a lot of faster Pokemon. Pheromosa, Latios, Dragapult, and Tornadus-T are pretty good offensive checks that thrive right now. What I do take issue with, is how ridiculously difficult it is to switch into Landorus defensively. The only Pokemon somewhat capable of checking Landorus defensively are Cresselia, Latias, Chansey, and Moltres. However, it has pretty solid ways to get past these bar Cresselia; Latias takes a lot from Sludge Wave, Chansey's Eviolite can be removed with Knock Off, after which it is 2HKOed by Focus Blast, and Moltres folds pretty easily to Sludge Wave, Psychic, and Rock Slide.
As I noted earlier, I am not convinced Kyurem-B is broken as of right now. It is obviously very potent, but I think it struggles a fair bit because of the pacing of the metagame. Oftentimes, setting up a Dragon Dance is really hard, such as against the team I shared above, where it'll practically never manage to set up a Dragon Dance, and even if it does, it can be taken care of by strong priority users and a Choice Scarf like Latias. It isn't just that though; even when Kyurem-B manages to set up, it can still really struggle to get past Melmetal and Magearna. Earth Power is an option to weaken those Pokemon for a sweep later down the line, but I've generally found Earth Power to be pretty hard to afford, as Substitute is very important in order to set up on Chansey and Blissey, as well as to limit the effect that priority users have on Kyurem-B's chances to sweep.
