I just struggle to see why you would run this over the other psychics in the tier, namely Indeedee-F. Thick fat is nice I guess, gives it a good matchup vs charizard and it has some colourful coverage options but it's both weaker and slower than Indeedee-F, and this is before considering psychic surge which makes Indeedee-F's psychic attacks even stronger and protects it from priority. Its not awful but feels very outclassed to me.

I know we're strapped for hazard removal but like come on. If you want grass type hazard removal you have dartrix which also gets knock off, can't be spin blocked, has actual physical bulk and is actually capable of doing something offensively. Even carkoal gets dual hazards at least, toescool has spore I guess but good luck doing anything with it before dying. I haven't seen anyone run this since like week 1 and I don't know why you would run it.

Banette is a very overlooked spin blocker in favor of misdreavus for obvious reasons, but I feel like knock off access is a big enough draw to justify itself on hazard stack. Very few mons in the tier get knock off and with how many mons carry boots being able to knock them off is hugely beneficial for hazard stack teams. Your other options for this are dartrix which isn't a great fit on hazard stack and tinkatuff which is great but pretty passive and therefore sometimes hard to fit. Its bulk isn't great but when invested in it's good enough for what it needs to do, and it can still be annoying with spreading burn or paralysis. Obviously misdreavus is generally far superior, but banette is good enough to justify itself on certain teams who really appreciate the knock off support. (It also doesn't need to run eviolite which frees up its item slot but its probably just gonna run boots anyway which misdreavus probably wouldn't even if it didn't need eviolite)
