Alright I think I see...you're on Free Battles on Battle Spot Doubles, right? I made the mistake of assuming Rating Battles on Battle Spot Doubles/Special. It's a little tougher to give advice for Free Battles, since it's not really much of a format since ANYTHING can be brought there, including a team of 6 ubers that would likely crush the 6 Pokemon you currently have (including Kyogre) no matter what, or Lati@s with Soul Dew, an item that is normally banned.
As for my recommendations for Battle Spot Doubles Rating Battles (aka VGC15 back in the day, and Kyogre is banned in this format)...Typhlosion should really be 1 of 3 things...Timid with a boosting item (Charcoal is fine, but Life Orb (which is taken up by Thundy right now) or Choice Specs really help him a lot more), Modest with a Choice Scarf to fire off at least one full health Eruption, or Modest with speed control support. T-Wave on Thundy is good, but you could really use a second form. Minimize is not something I like on Clefable. While it can be annoying to your opponent, it relies completely on luck. I would replace that with Icy Wind. Most (unboosted) Pokemon at -1 speed will be outsped by your Typhlosion then. Coming back to Typhlosion, unless you are going to be Scarfed, I would replace Rock Slide with Protect. His attack stat is mediocre, and is even worse with a Modest nature and no investment. If you end up going Scarf, replace RS with Focus Blast (not normally a move I suggest in doubles due to the accuracy, but he doesn't really have any other options, unless you rebreed for a Hidden Power).
AV Gardevoir is not very good. Since you can have 2 megas on the team and only need to bring 1 then, definitely stick with the mega. Having both Hyper Voice and Dazzling Gleam doesn't really make sense either, so drop D-Gleam for Protect. Again, I don't think Focus Miss is very good, so you should consider something like Shadow Ball (or HP Ground for Heatran) instead. Definitely use an Ability Capsule to get Trace. Telepathy doesn't help you since you don't have moves like Surf or EQ, and Tracing things like Intimidate or Swift Swim can really benefit you before you mega evolve.
Is there anything in particular your Clefable spread does? I'm more of a fan of Sitrus for a Pokemon like Clefable, but Leftovers can be ok too. Really comes down to personal preference. Magic Guard isn't bad, but I've always found Unaware to generally be more useful since you can ignore stat boosts from things like PuP M-Kang or BD Azumarill with Follow Me if Unaware is your ability, which can buy your team some more turns to take out those threats instead of being steamrolled once they boost. I would replace D-Gleam with Moonblast, and Flamethrower probably isn't necessary since you have fire coverage elsewhere and Clefable should really only be out there for speed control and to use Follow Me. Protect, Helping Hand, or Thunder Wave are all solid options.
Thundurus looks pretty good, though Grass Knot is sort of redundant in this format. HP Ice is a much better option.
Again with Kang, EQ is a wasted move in doubles with no Parental Bond effect, and PuP or Low Kick are generally better than Drain Punch. You can consider Double Edge for the extra firepower as well, unless you do go with PuP, in which case I would say stick with Return.
Aegislash looks solid too, tho definitely consider the nature change like others have already suggested. If you want to be min speed, move those 4 speed EVs into SpDef as well.
Now as for Battle Spot Special Rating Battles (which is also currently the same as VGC16)... P-Kyogre is a great restricted legend. Your current spread doesn't really make sense though. A Quiet nature with some speed investment is counter-productive. If you stick with Quiet nature, you'll probably want to run Trick Room, which would change a lot of things on your team. Without TR, ideally you'll want a Modest or Timid nature. There isn't really any time to use Calm Mind in this format, and Kyogre has massive special stats already. Protect is definitely needed there, and since you already have Thundurus with an electric move, I don't think Thunder is a requirement. Water Spout generally goes fairly well with a fast Kyogre, and then you can keep O-Pulse or try Scald for a 100% accuracy move you can use at lower health or to avoid Wide Guard.
If you want to keep Typhlosion, you'll probably have to do 1 of 2 things. Either never bring it to a battle against an opposing P-Kyogre (and really you can't attack with it with your own Kyogre on the field either), or have an Air Lock (Rayquaza) or Cloud Nine (Golduck is the "best" one, which isn't saying a whole lot unfortunately lol) Pokemon. Typhlosion still can't really touch P-Kyogre even with this support though unfortunately :/ I'm all for using unique or your favorite Pokemon and strategies (I've ranked very high with a Parasect and M-Scizor this year, and done fairly well with things like M-Gallade and Lapras in VGC15), but some things will just struggle, which is why I suggested sticking to Battle Spot Doubles if you want to use Typhlosion.
For a 2nd restricted legendary, P-Groudon is king right now and dual Primal teams are very good (this would greatly help your Typhlosion too), Rayquaza is very good (even as a non-mega if you bring another mega to the battle, and the "Ray-Ogre" core is very strong), and Geomancy Xerneas is essentially a better M-Gardevoir this year. There's other restricted legends that can work or have had success, but those are the "big" ones. M-Kang is very good in this format, so you may want to keep that as your mega instead. Thundy and Aegislash are still solid options here. Aegislash may want Iron Head or Gyro Ball to deal with opposing Geomancy Xerneas better, but Thundy should be ok (Protect, HP Ice, or HP Water are likely better alternatives over Grass Knot though).
One final thing I'll add for both team suggestions is that you seem a little Trick Room weak IF it goes up. One potential solution to to use Clefairy over Clefable. While you're unfortunately stuck with Eviolite, they are otherwise pretty similar and Clefairy has a better ability in Friend Guard to support your team. Most importantly, Clefairy is slower and can use After You to help your other Pokemon attack sooner while under TR.
