Okey-dokes, got some fiery stuff here that I should preface probably isn't the best since weather isn't particularly strong, but they should be fun teams.
and his formatting style since it's pretty oo (also click sprites for importables)
Metagross-Mega Sand (could be an ORAS team!!)

Hi,
Psychobuzz! Okay, so this one was a bit of doozy to figure out. You seemed ok with any 'Tar + Ice-type move, so I experimented heavily with a bunch of Band 'Tar + Ice Punch builds but couldn't really figure out anything particularly interesting or effective. I figured I would try to play off of the pressure this 'Tar could potentially place on Lando-T and go from there, so a lot of my earlier builds with this were just Band 'Tar + SD Mawile; the major issue there was that Band 'Tar simply doesn't work as well as it used to and it shows in teambuilding really harshly. The builds were either really slow or had major glaring weaknesses, so I scrapped that and settled on some whacky sand build that for some reason has no fighting resists (it's fine, I swear!).
Since I was building sand, I wanted Steel-type defensive redundancy to compensate for how Excadrill is a pretty bad defensive steel in the conventional sense plus something that could pressure the myriad of checks Excadrill has now. Metagross-Mega fits the bill pretty much perfectly; it pressures stuff like 'Steela with T-Punch, Lando-T with continuous Mashes, and a few other things. This variant is HP Fire which is traditionally complete booty-cheeks but is painfully necessary for how weak this build is to Scizor. Next up, we have a glue pivot duo of Rotom-W and Tangrowth that help manage the abhorrent fat grounds weakness the team has so far accrued as well as key threats like Zygarde, Mawile, Scizor, etc. I don't really like weather with scarfers too much, and the team did a surprisingly good job of managing the speed boosting sweepers the tier is littered with, like Volcarona, Gyarados, and Zard-X, so all I had to do was find decent natural speed + something for 'Mence. Swords Dance Weavile, while a rarer pick these days, fits the bill nicely by providing a boosting sweeper to the team in addition to a solid speed tier.
The team's fighting resist is Chople 'Tar and it's pretty damn Greninja weak (but what isn't lol) so keep that in mind. It covers all everything up until A rank pretty decently and should cover most of B, so I think you'll be fine. It did pretty decently in testing.
Venusaur + Specs Heatran Sun

Yo,
MilkyWay. Got your sun team here. This was interesting to tinker with, but I feel like this is ultimately the best version of what I've constructed thus far despite some obvious flaws, but that's pretty much inevitable with sun. My original idea was Dugtrio + Volcarona + Torkoal, but it's relatively annoying to account for the scarfers that Volcarona is RK'd by—that idea was scrapped. I moved onto the idea of Chlorophyll sweepers soon after after I remembered having success with a troll sun team TDK pasted that featured Venu + Victreebell.
I honestly kind of forgot how I built this version, but the starting point here was—I think—Torkoal + Dugtrio + Cresselia. Sun is inherently going to be a very janky playstyle that is going to be strapped for threat coverage, so something capable of massively blanket checking the meta, like Cress, is practically mandatory. From there, I added the best Chlorophyll sweeper, Venusaur, Specs Heatran, and Scarf Terrakion to round out threat coverage. I apologize for this being particularly non-descriptive teambuilding process—this was the product of lots of tossing together a bunch of possible builds and seeing what worked best in theory and in practice. I ultimately decided that the pressure a Chlorophyll sweeper exerted + something to wallbreak with sun up was best to optimize offensive pressure output, so that's why 'Tran + Venu are there mainly.
Ash Gren is a massive headache and your only ground resist is Cress (!!) so be careful there. Stall will also be a major frustration but I don't think a viable sun team could get around that well. My sun teams did well in testing so hopefully it works well for you! Do note that there is a slash in Venusaur's moveset; you'll have to manually change that in the paste before actually importing if you want it to properly register in PS!.
