You should paste you're team in https://pokepast.es/
And read the rules first

https://pokepast.es/d6b00a7e56bf10c9(This is my first team rate don't expect too much)
You're team looks like Hyper Offense so I'll make you're team HO
First is your lead/Hazard Setter, the lead you use in your team is Primal Groudon but I think Pdon is better as a sweeper than a offensive rock setter.
Here is the leads you can choose from : Deoxys-S, Excadrill, Ultra Necroza
Stealth Rock setter >

Marshadow can be good but with so many offensive mons you need to replace it
(Note: If you are going to use Ultra Necrozma as your Stealth Rock setter replace Marshadow with Xerneas and use the button below for the replacement set)

Set

Necrozma-Dusk-Mane @ Ultranecrozium Z
Ability: Prism Armor
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Stealth Rock
- Photon Geyser
- Heat Wave
- Power Gem / Dragon Pulse

This set is an offensive set that can chip your opponent while setting up rocks

The next set is you're Pdon set, the reason it's better as a sweeper is because in HO you aren't using it's defensive qualities and more on 6-0 you're opponent with fast, strong hitters

( Click image for the set )


Next is the team's weakness to webs because hazards annoying as hell, you can easily use a defogger using Mega Salemence, and you really, really
need defog support


And one last thing
If you are using an Excadrill/Deoxys-s lead, you can either change your Necrozma set, or replace it with Xerneas

So basically the team structure

/

+

++/+

/ +++++

Overall I think you're team is quite good. I don't think you need to change any of the sets you use
