Mega Rayquaza: I think if we are striving to make the tier more enjoyable and playable then keeping mray banned is the obvious choice. It would be fun to try in a suspect but the only real point I can think of that would benefit a suspect is basically unbanning all previous mons/restrictions then deciding on what is unplayable and unenjoyable. But I think it's clear mray still has a way bigger power gap between the strongest threats of ubers nowadays which are pdon, xern, maybe necro depending on how the meta turns out.

Species clause: Seems way to chaotic to unban. I know people spam arceus in ag to help vs mray and if mray was unbanned would arceus spam be neccesary? I have no clue but I don't really think that unbanning species clause would be healthy as it promotes more usage to the strongest and most versatile mons which leaves behind a huge chunk of mons that would get no usage. It also doesn't seem like it would be enjoyable for obvious reasons. Do I think species clause is broken in a way? Definetly. I don't want to have to face two geoxerns that each bop each others checks for example. Magearna can only beat one of them and I bet one of them also has thunder for hooh etc. I think it would be best to keep it banned.

Primal Groudon: I've been saying this since oras that the reason pdon has a really high usage is because of how splashable it is. I think it's extremely annoying and can beat any of its checks with the right coverage making each team to bring 2 switchins and usually some way to revenge kill. I don't think it's broken though. It has plenty of checks and sure they can outright be beaten by them but that's why people have adapted to running numerous checks. It can get sr up almost always but if you can lay a toxic on it as it gets rocks then it's timer is on and then becomes less of a threat. Especially if you had like mgar to just trap and hex it. I think because of how great of a sr setter he is that in the past most people end up trading rocks rather than fighting to defog unless it's stall or balance that absolutely needs rocks off. In usm I can't tell if it's gonna be as good especially with duskmane being an extremely effective sr setter. Between new sr setters and way more defog options it possibly might drop in vb when it comes to being the most effective sr setter. It will always be an offensive threat though but for balance/stall the sr set was always the most dangerous set to face. Do I think it makes the tier unenjotable or unhealthy? I think in oras/sm it was actually healthy to have pdon but hard to tell for usm. I never thought it made the tier unenjoyable but I can see why others would think that.

Geomancy: I think people overreact when it comes to geomancy. I think it doesn't sweep as much as people think if it's reg geomancy but it can definetly help with breaking the opponents team but to sweep it needs support just like any other sweeper. There are plenty of checks and even a "counter" that can't get trapped by mgar/goth but obviously it can get worn down since it's used to check other threats such as yveltal. It definetly restricts teambuilding because you need not 1 check or 2 checks but usually 3 checks unless offense I guess which usually just has pdon + priority. Zgeo can sweep very easily vs unprepared teams and doesn't even need support to do so. It restricts teambuilding a lot more I guess. For an example sd on scizor is used specifically for zgeo but overall there are other better coverage moves or status that would benefit scizor a ton if they could run them. Thimo decided to opt to run one of those better moves rather than sd on sciz vs ttg in snake and got easily beaten by zgeo. I think it makes building more unenjoyable but not as much as people would argue. I don't think it's that unhealthy for the tier especially considering spd solg seems to be rocking in usm and that scarf xern looks WAY better in the meta but I think we would have to wait till the meta settles.

STAG: I don't really wanna write out a huge amount of discussion on this one topic so I'll keep it short with my biased opinions and let others talk on it more if they wish too. I think mgar would be deemed unhealthy if the mons that it trapped didn't have a way to beat it, if it had stag before mega evolving, and it couldn't be pursuit trapped. But because it doesn't have these things I think it's healthy as it allows you to have a nice revenge killer and an effective balance/stall breaker that isn't deadweight vs offense. It takes skill to continuesly remove threats with mgar without it getting chipped so I don't see the problem with mgar. Goth has stag right away, it can remove mons without removing them (pp stall them) then use them to get a free turn to setup or set rocks or whatever, it can't be pursuit trapped unless you manage to double a pursuit trapper in(goth will most likely pp stall then switch out before it struggles to death to give the player a free turn). I think it was unhealthy and unenjoyable for sm and I think once the meta settles it will be just as good or slightly less in usm. I think goth deserves a suspect test a month or 2 into usm when it has settled more and if it's not broken enough to be banned I think you might have to comeback to suspecting it later on once the meta develops more. Goth was good at the start of sm but wasn't common or used a lot till later in sm but now that we know what goth can do I think the second balance or stall is used more than once every 10 matches or so then goth will make a return.
