I mean Shell Smash + Baton Pass is pretty stupid and if we haven't touched it yet it was because nobody really tried to abuse it too well and wasn't really that popular as a result and because we had some more important tests to do.
It is no mystery that after Dual Screens are set up or with Memento support Huntail has no trouble at using Shell Smash an Baton Passing sometimes even with a Substitute up and if entry hazards are up to break Sturdy and Focus Sashes pretty much anything with a decent STAB move can clean up. Stoutland and Simipour are the main two I have seen being used (and I did use myself) and they absolutely tear apart most offensive and bulky offensive teams after a boost (Stoutland can also use Lum Berry to get around Kadabra) and the fact that the team structure presented also lets other setup sweepers thrive (such as Linoone for example) it can be pretty clear how we want to nerf this strategy i.e. putting an end to it.
SmashPass was also banned in NU and RU last generation for similar reasons and I am pretty confident the council will unanimously choose to ban it.
