Why are so many post assuming you want to switch your spinner into the spinblocker?^^ It's the other way around! :D
Also there is so much other counterplay to hazards than attacking the incoming spin blocker, e.g. HDB, Magic Bounce, Magic Guard, (Magic Coat), Taunt, Setting up your own hazards, use the free turns while the opponent sets up hazard to set up with a sweeper...
It's really not that hard to prepare for hazardstack, if you don't default to Corviknight which is blanked by Gholdi...
Just embrace the changing metagame, adapt to it, and don't be so lazy ;)
Magic Coat does not exist anymore. Magic Guard is not on any notable Pokémon, and if it were, it's not solving the hazard issue, if Taunt was a reliable means of hazard control it would be prevalent in every generation for this purpose (it is not). Boots do exist, but in a metagame where recovery is limited, having those free leftovers turns count now more than ever. "Use the free turns to set up a sweeper" what in the world are you talking about? I'm convinced people are just saying these without meaning anything because 3/4 of what you said is non applicable nonsense.
Magic Bounce is the only thing I'll give credit here, Hatterene is a decent underrated pick in the metagame right now. It hates Glimmora that run Sludge Bomb, but those do not seem to be the main move it runs right now so Hat can get by. Outside of Glim it has an ok matchup with other popular Spike setters like Clodsire, being able to comfortably beat non Poison Jab/Gunk Shot variants with Psyshock. My problem with it right now is how prepped people are for Pokémon of it's typing, Ghost types are EVERYWHERE, it's a Fairy type that can't switch into Darks and Tera Steel is one of the most popular Tera types in the game. But if this is what people gotta do in order to survive the hazard warped metagame, so be it.
Like most people are saying, if this thing existed in Gen 8, it would not be a problem Pokémon. All the common defoggers would have reliable means of combating it, and honestly most of the pivots in Gen 8 used Boots. Now though? Hazard control was hyper constricted, while hazards became hyper distributed, lopsiding the hazard game completely in the setter's favor. There should always be balance, and until these hazard control options of the past are here to combat it, I just do not think it's an overall positive impact on the metagame.
