Suggested bans:

On paper it seems fine with espeed users like entei and dnite fake out incin grassy glide rilla etc but with indeedee this thing is super broken. This has a million coverage moves to beat whatever it wants, and with follow me support this thing is unstoppable. Way too fast and strong, it even has espeed to deal with faster things.

Same vein as deo a except you have bulk to live espeeds, rilla grassy glide, double fake out or stuff like fake out+feint from sneasler

Really good setup sweeper and support mon. It's best answers are Urshifu and Chi yu... and they're both banned. This means that you have to double target to ever kill this thing (252 Atk Choice Band Sword of Ruin Chien-Pao Crunch vs. 252 HP / 252+ Def Deoxys-Defense: 254-300 (83.5 - 98.6%) -- guaranteed 2HKO lol) and if you don't, it'll get a trick room to enable Ursaluna Torkoal or whatever trick room sweeper you need, can enable weather teams or do whatever it wants really.

Just a better dnite with amazing coverage moves, a good spread move and a broken ability. I've been running power herb meteor beam for all of the fire types, but you can run cm covert cloak, specs, or even run a weather move like raindance/sunny day. It just fits onto every team and without fighting types (ihands shifus) this is too much.
Suggested unbans:

This would be a very healthy addition to the meta, we need a good fake out user and the meta just checks this naturally. We got psyspam looking really good, fire types that hinder ihands (gouging fire swipes, incin intimidate, sacred fire entei, etc) and lots of new special attackers that would probably force ihands to always run av instead of the sd set that got ihands banned. We really need fake out mons and a good fighting type.

(water) We got a lot of new checks/counters like rilla, raging bolt, all of the ogerpons, psychics etc. In return we get a really good water to check all of the fire ground dark types that are omnipresent in the tier. I do not see a world where this is broken.
Controversial opinions

meh doesn't seem that good with all of the faster mons that exist now and with other fire types having competition with this, we need darks for psyspam and theres lots of new checks with water rock ground fighting etc. Is it too good by enabling its teammates like flutter to become really good? maybe but we need a good answer to indeedee so unban pls

This is fine, we have hoopa u which is probably better than this tbh, but this is a good dark and good fighting type with decent priority with sucker punch. May be a bit too good but I think it contributes more than it takes away.

Maybe it's just me but I don't really see what this enables to be really good. Like there's lots of rock electric and ice types that just counter this thing casually, and with the meta going into a more bulky phase this doesnt seem that broken. Then again it got a pretty nice coverage move in bleakwind storm so idk
maybe also

or

but idk
