What new tools are there? Paldea Tauros isn't a good pokemon already in the tier (it dropped on the vr post Pao ban), and HOME to my knowledge isn't bringing anything either so I'm not seeing it.
Magearna (if it stays) and Watershifu are new checks. And Zamazent (also if it stays).
Tauros dropped after Chien Pao left, it will rise when Chien Pao returns. Yes, its otherwise not a very solid Mon, however it is an almost (weird Tera being exceptions) a surefy stop.

Back when Chien Pao centralized the Tier, I used this guy a lot ( in fact, both the Tera Suspect Reqs and the Chien Pao Reqs I got with Tauros on my team). It does not only stop Chien Pao either. It also completely nulifies non Tera Blast (or the also rare Zen Headbutt and Grass Knot) Kingambit, which is currently a Top 2 Mon (in Chien Pao Meta it was worse though). Very often while using this, I could run into both Chien Pao and Kingambit. This meant those games started 6-4 in my favor, very rarely either of those could break it.
Other Mons it stops:
Tusk (some sets).
Baxcalibur (shaky)
Roaring Moon (non Flying variants).
Cinderace.
Already Tera'd Nite.
Ceruledge
Floatzel (extremely hard to stop Mon for most teams without immunities).
There is also Fire variant, which I consider worse, but has WoW.
Despite being Restalk, Water Tauros was not limited to Stall teams, and worked quite well in balance, supporting with Intimidate teammates, that could now switch-in easier.
Theorymoning with Tauros regarding new Mons, it can also check Hisuian Arcanine, Hisuian Samurott, Kleavor and is a shaky switch-in to Sneasler, Zamazenta, Ursaluna, Basculegion and Watershifu.
So, I don,t see this guy bad at all in the context of a Meta with Chien Pao in it, its not like its job is only to stop the cat.
Back to Chien Pao, even with new checks it might be too much, I can admit that. However, its not an obvious Ban for me like Landorus-I, Spectrier or Annihilape, we don,t lose anything by testing it and I can see it providing something positive for OU, that being keeping in check offensive teams while not being as good (but still very viable) vs more bulky ones (its similar to Zamazenta in this regard). If its too much, it can always be banned again.
