How can I improve my gimmicky Gen 9 Uber rain team (without losing the gimmickyness)?

Quick rundown of the rationale and purpose of every Mon and build:

Banded Palafin: wallbreaker, (only) priority user, i mean its main thing is just that it hits hard, it’s also the second most likely to get Tera’d, i usually send it out first then flip turn into Pelipper.

Pelipper: rain setter…duh.

Iron Treads: mainly hazard removal, also checks electric types and Thunder users.

Scarfed Kyogre: wallbreaker or revenge killer depending on context, also acts as a backup rain setter.

Kyurem-W(ater): my wild card and sorta what the team is built around, weather ball in rain and freeze dry have practically perfect coverage (and Turboblaze bypasses Water Absorb) and hit very hard with a life orb and max SpA investment (especially with Tera Water), scale shot and sub are more situational but could facilitate a sweep if I can get them off.

Now Kyurem has a lot of flaws, one of which being that this build is quite dependent on rain but again it is sorta the whole point of me making this team so I’m not swapping it out.

Scarfed Zapdos: fast offensive pivot to apply pressure while returning to a rain setter, Hurricane and Thunder also hit very hard.

I should also mention that I also intended for this team to have as few very meta Mons (Koraidon, EKiller Arceus, etc.) as possible but I am open to adding one or two if there’s even a good spot to slot them in.
