I was gonna save this discussion for when the tiering thread became unlocked again but I think a mon that I've discovered to have a very important niche is Wheezing-Galar. Besides the Neutralizing Gas set that it is known for, I experimented with using it with Misty Surge when KyuB and Melmetal were around to prevent them from getting statused. Past their ban though, Wheezing has continued to be useful for the same reason with any other sweeper oriented team. Especially with the new influx of Toxic users, having Misty Terrain up frees switching immensely. Hydreigon comes in on Toxapex and Seismitoad for free for example.
Its main flaw being that it is a bit of a Politoed, not much of a mon in itself and more useful just to send out for the terrain. But it does have a great utility pool that allows it to do useful stuff if it can come in safely or as a last ditch effort. I typically run Defog/Aromatherapy/Memento/Strange Steam full SpDef invested. Full Def investment works too, I just think since I only need it to usually survive one or two encounters I'd rather have it decently bulky on both sides instead of specialized. If you have other hazard control or feel like you can keep status off the whole time, you could run something like Fire Blast or even Will-o-Wisp as if you defog, you unfortunately get rid of the terrain.
Arguments against it that don't turn out in practice are that Defog is more available now as well to get rid of terrain. I've found that if the opponent goes for that, you have a super free switch-in that gives you two turns of setup. Which is all you need usually.
The other 2 mons that I've found have become significantly improved since home are Mantine and Mew. Mantine might be somewhat obvious due to its rain usage but outside of rain I've found the niche of being a Water Absorb mon with Defog and recovery to be super useful. With Heavy-Duty boots it's a pretty killer mon and running full physical bulk actually makes it pretty formidable coming in on resisted hits since it retains a lot of special bulk still.
Mew on the other hand, gaining access to recovery has enabled probably its most devastating set: full Def, CM stored power. In tandem with Misty Surge and screens or just a reliable Aromatherapy user, Mew 6-0s many teams without a ridiculous physical breaker like Dracovish or Darmanitan in sun. The latter Mew can beat out of sun by just recovering off Flare Blitzes while Darm kills itself provided its not banded. Mew can survive scarf Dracovish quite comfortably from full and at +2 it OHKOs with stored power. The secondary attack I typically run is Aura Sphere which allows it past powerful dark types like Bisharp, Tyranitar, and Obstagoon which it can survive provided it is healthy. The alternative is Draining Kiss which gives it a better matchup into Mandibuzz.
Blunder played against me recently in a vid which showcases these two although you can see some of the limitations, I think my Misty Terrain team sets up Mew a little better.
