What can I do to improve my DUU team?

Question

The team is as follows:
Ceruledge @ Life Orb
Ability: Flash Fire
Tera Type: Grass
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature
- Swords Dance
- Bitter Blade
- Solar Blade
- Shadow Sneak

Ninetales @ Heat Rock
Ability: Drought
Tera Type: Ground
EVs: 4 HP / 252 SpA / 252 Spe
Modest Nature
IVs: 0 Atk
- Baton Pass
- Scorching Sands
- Nasty Plot
- Helping Hand

Noivern @ Throat Spray
Ability: Infiltrator
Tera Type: Dark
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
IVs: 0 Atk
- Boomburst
- Dark Pulse
- Tailwind
- Moonlight

Lurantis @ Ability Shield
Ability: Contrary
Tera Type: Rock
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature
- Leech Life
- Superpower
- Tera Blast
- Petal Blizzard

Grafaiai @ Black Sludge
Ability: Prankster
Tera Type: Flying
EVs: 252 HP / 4 Def / 252 Spe
Timid Nature
IVs: 0 Atk
- Scary Face
- Parting Shot
- Encore
- Super Fang

Zoroark-Hisui @ Focus Sash
Ability: Illusion
EVs: 252 SpA / 252 Spe
Timid Nature
IVs: 0 Atk
- Hyper Voice
- Nasty Plot
- Icy Wind
- Curse

The main idea behind grafaiai is that it uses scary face into lurantis to double it's low speed stat and has pulled off a few sweeps.
The main idea behind ceruledge is to use it as a bait for water types and then hit them with helping hand boosted solar blade.
And the idea behind zoroark is it uses nasty plot on the same turn that noivern uses tailwind, and then theoretically sweep using boomburst and hyper voice, with icy wind on zoroark and tera dark dark pulse on noivern for ghost coverage.
My main concern is I feel like the team is too disconnected, despite me trying to connect then best I can, and I'm honestly considering making it three separate teams, but I'm fairly new to team building and I'm afraid I'll ruin the best team I've had.

There's an issue that you instantly need to solve, add Protect to your pokemon. If you don't, your pokemon are gonna be sitting ducks infront of Fake Out users that can stop your pokemon from doing anything and let their partner set up or just delete one of your pokemon. No Protect also means you can't reposition in a bad situation.

Thank you, I've added protect to lurantis, zoroark, and ninetails. Would it be beneficial to add more pokemon that know protect?

---

In general you would want Protect on all your pokemon, it's just that important.

Read this if you want to know why protect is so good in doubles

https://pokemondb.net/pokebase/440060/why-is-protect-used-so-much-in-doubles?show=440061#a440061


Also a lot of the sets seem kinda odd. Like curse on zoroark or no stab on nintales but I don’t know about Doubles Uu for a full rate

---

Yeah, I dropped curse for protect, but the reason I had scorching sands rather than stab is I was having a very hard time hitting fire types aside from tera blast rock on lurantis.

I think dropping Lurantis for Superior would be better overall as Serperior doesn't need as much help from it's teammates due to already being fast, and can snowball from Leaf Storm. Whether you use Superior or Lurantis, I would recommend Stellar Tera for Tera Blast, as that can push their snowball to new levels as you can't resist Stellar Tera Blast.
