Rate my mixed Gen 9 VGC set F team

Question

Amoonguss @ Assault Vest
Ability: Regenerator
Level: 50
Tera Type: Steel
EVs: 252 HP / 4 Def / 252 SpD
Calm Nature
IVs: 0 Atk
- Clear Smog
- Giga Drain
- Rage Powder
- Toxic

Amoongus' role is to 'wall off' any faster sweepers with clear smog to prevent set up sweepers and rage powder to let my other sweepers well, sweep. Tera steel because it is the best defensive typing

Incineroar @ Weakness Policy

Level: 50
Tera Type: Flying
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- Acrobatics
- Darkest Lariat
- Fake Out
- Bulk Up

Incinerator is my set up sweeper. Acrobatics to counter fighting mons, darkest lariant for STAB, and bulk up to set up, WP is to raise stats even mor eif it does get hit with a supereffective move

Primarina @ Throat Spray
Ability: Liquid Voice
Level: 50
Tera Type: Normal
EVs: 252 HP / 252 SpA / 4 SpD
Modest Nature
IVs: 0 Atk
- Hyper Voice
- Dazzling Gleam

Sweeper/support. Hyper voice to active throat spray, liquid voice to increase the damage of hyper voice even more, dazzling gleam for STAB, ice beam for grass types and coverage and life dew for support and healing

Magnezone @ Light Clay
Ability: Sturdy
Level: 50
Tera Type: Electric
EVs: 252 HP / 252 SpA / 4 SpD
Quiet Nature
IVs: 0 Atk

Magnezone's role is to set up reflect, lower speed with electroweb, as well as flash cannon and thunderbolt for STAB

Salamence @ Aguav Berry
Ability: Moxie
Level: 50
Tera Type: Poison
EVs: 252 HP / 252 Atk / 4 SpD
Brave Nature
- Dragon Claw
- Dragon Dance
- Iron Head

Another set up sweeper, dragon dance to increase speed and attack, claw for STAB, iron head for fairies, earthquake for steel and rock types. Tera Poison in case the opponent tries to hit it with a fairy attack

Cresselia (F) @ Leftovers
Ability: Levitate
Level: 50
Tera Type: Ice
EVs: 252 HP / 252 SpA / 4 SpD
Quiet Nature

Another wall that can also set up trick room if both my sweepers are gone, dazzling gleam for fairies, icy wind for more speed control and physic for more stab

Comments

So, I'm not answering right now, but here are some things that i wand to mention:

Amoonguss - Why do you have status moves with Assault vest? That doesn't work, so replace Assault vest with Rocky Helmet. Toxic is inferior to Spore in my opinion. You can probably change the tera type to Water too. Also, I think physically defensive Amoonguss is better then specially defensive since Cresselia can be the specially defensive one.

Incineroar - So, since Incineroar is supposed to be more of a support mon, go with a set like this:

Incineroar @ Sitrus Berry
Ability: Intimidate
Level: 50
Tera Type: Flying / Bug
EVs: 252 HP / 252 Def / 4 Atk
Impish Nature
- U-Turn
- Snarl / Flare Blitz
- Fake Out
- Knock Off

Fake Out can stay since its Fake Out. U-Turn allows you to pivot. Knock Off is STAB and gets rid of items. Flare Blitz is STAB, but you can opt for Snarl to cripple special attackers.
Primarina - Why tera Normal when Hyper Voice becomes a Water move anyway. I think Tera Ground works good.
Magnezone - There isn't much of a point in using Light Clay with only 1 screen. Even then, mons like Grimsnarl do the job better.
Salamence - There is no point in using a Brave nature instead of Jolly / Adamant. Also, since its doubles, you might consider Intimidate over Moxie.
Cresselia - Trick Room isn't actually a bad idea in this team if you make sure to not bring Salamence. However, don't use a offensive Cresselia please. Change it to something like this:

Cresselia (F) @ Leftovers / Mental Herb
Ability: Levitate
Level: 50
Tera Type: Dark
EVs: 252 HP / 252 SpD / 4 SpA
Sassy Nature
IVs: 0 Atk / 0 Spe
- Lunar Blessing
- Trick Room
- Ally Switch
- Psychic / Psyshock

Very annoying to face. The item can be Mental Herb to prevent Taunts, but Lefties is fine too. Tera Dark gets rid of some weaknesses. Trick Room for obvious reasons. Lunar Blessing to heal. Ally Switch to play mindgames. Psychic / Psyshock so it can still do damage. EV's and Nature changed to boost special defense.

So, this is all the advice I can give for now. I'm probably missing some stuff, like the lack of Protect in your team, but that's all I can give for now.

The problem about using grimmsnarl as my screen setter is that primarina and grimmsnarl both share its fairy typing.  So instead i just replaced thunderbolt with light screen
