eh just gonna bump this because i do have some actual insight after picking up the metagame with this team + calloflochies changes and it doing quite well for me.
for reference: pert / aroma / tspike forre / subcm chande / cbhera / scarfhydrei
p nice example of balance. subcm chande + hera, compounded upon hydreis fast checks, scald, and potential hazards gave me enough pressure to beat just about anything and the core is solid enough to where i can go at my own pace thru the midgame. i often felt like hydrei was weak linking even though its typing for chande and the aforementioned fast checks, especially with uturn, are crucial at times. my only other complaint was not getting more defensively out of the hera slot, but hes such a fucking threat and his ability to force the issue whenever he hits the field is a great boon, making it really easy to dictate games paired with the teams defense and momentum.
theres only a few threats i feel the need to address as this team is p close to as good as it can get.
-m-blastoise is incredibly annoying to switch into as bold aroma is hard pressed to stall it especially with scald and pulse confuse hax. aroma really just buys time unless u get a spatk drop but sometimes they are scared away for whatever reason. it never really put me in a position to lose tho between chip dmg, wish passing, threatening with hera and at least being able to trade it for severely crippling tortoise. ppl often lead with it too giving u a free window for hera lead.
-the occasional nidoking was p gay because of its speed + hydrei not killing + its coverage shitting on everything, and it shuts down tspikes for good measure. idk fuck this mon.
-suicune is also tentatively dealt with by pert and hera, tho i never lost to it either by preserving hera or eventually snatching the chande sweep, which is a p relevant point that u have a threatening sweeper to put a timer on and make it more difficult for cune to just try and outlast niggas. the recurring theme is i dont like how the team deals with scald because the damage is pressurizing and the only water resist is hydrei whos lack power and feels like a not ideal response. i guess aroma + wish and guts make it work but it hindered my switchability and made it easier for the opp to seize da momentum.
-ill just throw on empoleon + hera counter, which was a core i found hard to threaten. mixed fires too even though i think theyre covered here almost as best they can be.
fixes which are more "fun options i think are worth testing":
-defensive seismitoad over pert to manage waters better. sr / scald / equake / protect or knock off. idk if the diff in bulk is that noticeable as toad is no slouch with protect potentially helping to close the gap. meh.
-eviolite haunter or mismagius over chandelure. like for haunter which should be nicknamed porca bolognase, sub / shadow / sludge / split, and missy can set up. this change obviously seems like it sucks but auto losing to nido isnt fun and they can both kinda fulfill the same offense while being more nonstandard now that subcm chande is gonna be prepped for. chande is p superior offensively and is nice for pivoting or shitting on fires. ok yea this isnt worth it but who kno. eh and u kinda lose to bp lucario if thats a thing without it.
