Got some games under my belt, time for some thoughts

This mon is actually really nice. It sits on a surprising number of OU mons like Meow, Tusk, Garchomp, Sneasler and is a pretty nice switch to a bunch of new mons like Ogrepon, Okidogi & Fezandipiti. It's able to Defog, Cripple things with Wisp or Toxic, Haze stuff and gets a decent offensive movepool with Fairy, Poison and Fire.

Haze is nice to have vs set-up sweepers. Although it's not a solid answer to bax, it can stop it somewhat at leats, unless the bax is tera steel. Dgleam is an option if you really hate missing 95% moves (why can strange steam even miss?). I've not yet tried out Pain Split but it's an option for recovery, since GWeezing is very likely going to eat some knocks. Other ways to handle this would be wish-passing. Surprisingly, I've found

a pretty good partner for it. Umbreon covers Psychic attacks whislt Weezing can take on Fighting, Bug & Fairy moves coming in. Main issue with these 2 is that they're pretty passive.
Wisp is probably better than toxic, but the option's there.
Also, Neutralizing Gas allows Weezing to defog on Gholdengo, and burn Bax. These are some pretty cool traits, however the ground immunity is much more valuable in my opinion, as it lets you completely sit on Tusk & Ting Lu

Okay hear me out. I don't think this guy is OU caliber. That said, it's very fun to use with Slowking/Glowking. Sneasler is the better option in general with 5 more atk and 15! more speed. What Mienshao can do though, is stick around for longer thanks to Regenerator. It's also able to run Life Orb a lot easier, meaning it's less prediction reliant than Sneasler. It's speed is pretty low for such a frail mon unfortunately, but it is enough to outrun a good number of mons like Chomp, Zapdos and Gliscor. It's main draw over sneasler, though, are Ice Spinner and Knock Off
Mienshao @ Life Orb
Ability: Regenerator
Tera Type: Fighting
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Close Combat
- U-turn
- Ice Spinner
- Knock Off
Ice Spinner and Knock handle a lot of would-be switch-ins to Mienshao, and Knock is always nice to make progress. Thanks to regen, you can play Mienshao as a knocker in the early game and pivot around with U-turn, then clean up later in the game. I pair it iwth Twave on Slowking/Glowking to remedy the speed issue. Ice Spinner lets it snipe the 4x weak mons like Lando, Gliscor, Chomp and DNite and is also nice to have as a contingency option vs other ground or grass mons
The main problem though, is that Mienshao folds to +2 Kingambit in the lategame lmao. That said, fun mon to use, I can recommend giving it a shot!
