There are actually several answers to Dazzling/Queenly Majesty. An Unaware mon is a decent way to stop them, barring something like Moongeist Beam and Sunsteel Strike popping into existence ofc (just pick a mon that can tank them), and they're already decent as-is; hell you can run Spectral Thief on these if you want to really punish your opponent. Prankster Haze is also a good way to deal with set-up in general in this meta due to priority taking a hit due to stuff like this, Psychic Terrain, and Dark-types being immune to Prankster-boosted targeting moves. Depending on the mon, Imposter may also help. Lastly, really bulky mons in general are also useful because they might be able to take a boosted hit, depending on the mon/set, and retaliate accordingly. There are, ofc, more niche answers (hi random sash!), but these are the best I can think of off the top of my head.Would priority blocking abilities such as Dazzling be banned? They could become a huge problem if a pokemon sets up and can't be stopped easily.
as for CFZ moves please get rid of these you can tell they're bad when I have to run a Volt Absorb Yvel on my team to be able to deal with them reliably even with a Prank regi that doesn't get 2HKO'd by genesis supernova (barring a crit) and 10 MV Tbolt; reasons are same as everyone else has stated so no need to repeat those right?
