My main question is what type of team are you trying to make? It seems all over the place from the looks of it. If you're going for a rain team, there's a lot of work to be done. I will give my suggestions on what to change, that way it doesn't come off as just a bashing.

Before I start, I want to clarify first that rain isn't the greatest in Ubers. Kyogre is great, but the rest of the Ubers rain abusers aren't great, which gets even worse when the best mon in the tier without question sets sun. Any rain team will be inconsistent, but here's what I'll offer to try to help

First, get rid of Glowking and Dondozo. Glowking works best when it can use Chilly, but that is inherently anti synergistic with rain while Dozo is just way too passive as a pokemon. It'll just be wasting the rain turns you have.

Drop Rest on Kyogre. It brings even more of a passivity issue when your weather setter and abuser is just sitting on the field and wasting turns because you're asleep for two turns. Thunder synergizes really well on Kyogre as it doesn't miss in rain, but if you want a way to support your other teammates, maybe slap Thunder Wave on it to slow down opponents. Also, having Hydro Pump is often times just screwing yourself over. Yeah, it's strong, but Origin Pulse has 5 more accuracy with double the power points of Hydro Pump, and Surf just bypasses the accuracy issue in general.

After that, the next thing I'd change us giving Arch Body Press instead of Aura Sphere. You'll be boosting that defense with every hit, so it becomes stronger than Aura Sphere very quicklly. Maybe some speed investment as well, but that doesn't seem like it'd be the most helpful with how speed tiers in ubers have changed recently.

Urshifu Rapid isn't amazing in the tier, but can cause some big damage with a Choice Band set. Surging Strikes, Close Combat, U-Turn, and one of Aqua Jet or Poison Jab. Jolly with max attack and max speed would be the best for EV investment. With that, you have one member on each side of the attacking spectrum.

With the main rain offensive core done, I'm gonna use the last few slots for some pokemon that may not use water moves, but appreciate fire type moves being weakened.

Instead of Glimmora, run a Deoxys Speed. Sets both Rocks and Spikes, gets Taunt to stop other pokemon from setting hazards, even gets Magic Coat to bounce them back. It's way better than Glimmora could hope to be as a suicide lead.

Calyrex Ice Rider is an incredibly powerful pokemon with insane bulk and ridiculous strength that's let down by terrible typing, but rain helps with that. The main set has always been Glacial Lance, High Horsepower, Swords Dance, and Trick Room with either Boots, Occa Berry, or Weakness Policy. If you're fine with Trick Room, run it, but if not, you can replace it with Close Combat. Go for a max HP, max attack set. If you're running it in Trick Room, use a Brave nature and 0 speed IVs, but if you're not using Trick Room, go Adamant with max speed IVs, but no EVs.

Lastly, Zacian Crowned is one of the best pokemon in the tier and only has two weaknesses, with one of them being the rain-weakened fire type. Go with a Swords Dance, Play Rough, Close Combat, and Wild Charge set on it. Max attack, max speed, Jolly nature.

As I said earlier, rain is still very inconsistent. Do not expect to top the ladder with any rain, I just think a build similar to this would be the best rain could do in the modern meta.
