Rate my gen 9 Ubers team. [closed]

Question

The team is mostly about setting up then out speeding and insta killing all of the opponents Pokémon.

Sneasler @ Focus Sash
Ability: Unburden
Tera Type: Flying
EVs: 252 Atk / 4 SpA / 252 Spe
Lonely Nature
IVs: 0 HP / 0 Def / 0 SpD
- Swords Dance
- Close Combat
- Dire Claw
- Acrobatics

My idea with sneasler was I send it out, it uses sword dance gets to 1hp with focus sash, and since it no longer has an item it's speed is doubled and acrobatics is doubled in base power. I decided to give it zero IVs in the defensive stats as I need sneasler to have it's focus sash activate.

Galvantula @ Focus Sash
Ability: Swarm
Tera Type: Bug
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Thunderbolt
- Bug Buzz
- Volt Switch
- Sticky Web

Galvantula was added to the team for just sticky web. As it helps the rest of the team out speed my opponent, after I put up sticky web and mostly likely activate my focus sash next turn I can fire off a swarm boosted stab bug buzz.

Scizor @ Metal Coat
Ability: Technician
Tera Type: Steel
EVs: 248 HP / 252 Atk / 8 SpD
Adamant Nature
- Defog
- Bullet Punch
- Knock Off
- Lunge

Scizor is on the team as a secondary hazard remover after excadrill with defog. Scizor also gives the team priority with stab technician bullet punch letting me pick off any low hp mons. And I have knock off and lunge to support by removing important items and lowering opponents attack, bullet punch+knock off really help take down the fairy and psychic type Pokémon.

Koraidon @ Loaded Dice
Ability: Orichalcum Pulse
Tera Type: Steel
EVs: 252 Atk / 4 SpD / 252 Spe
Adamant Nature
- Scale Shot
- Swords Dance
- Collision Course
- Iron Head

Koraidon is my only sweeper that can bypass focus sash without stealth rocks. I use swords dance if am in a good spot and then scale shot to do lots of damage and boost my speed and because of loaded dice scale shot is always a 100-125 base power move meaning it can take down many mons. Iron head is there so I have one move to kill fairy type Pokémon.

Deoxys-Attack @ Focus Sash
Ability: Pressure
Tera Type: Psychic
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Nasty Plot
- Psychic
- Dark Pulse
- Focus Blast

Deoxys fills a similar role in the team compared to sneasler as it uses it's focus sash to survive and use nasty plot and then one shot the rest of the opponents team. The only problem is to deal with steel or dark types I need to use focus blast which can be unreliable. It is also my only mon that can deal with physical walls.

Excadrill @ Life Orb
Ability: Mold Breaker
Tera Type: Ghost
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Rapid Spin
- Stealth Rock
- Iron Head
- Throat Chop

Excadrill is my main hazard remover with rapid spin, which after the speed boost can help take down any fairy or psychic Pokémon that my team struggles with. Excadrill can also deal with opposing Pokémon holding a focus sash by breaking the sash with stealth rock.

Comments

This team will not fare well in Ubers at all. Everything besides Koraidon (and Deoxys-Attack to a lesser extent) are not good at all in the metagame, the sets being bad not to mention. Galvantula is a worse Sticky Webs setter than RIbombee because it is not immune to Scale Shot which breaks Focus Sash and is used very often. Collision Course is worse than Close Combat/Low Kick because it's weaker and its secondary effect is almost never making a difference (Pokemon weak to Fighting are getting KOed by the other two moves anyway). If you really want to use viable teams in this format, I'd suggest checking out the resources:
https://www.smogon.com/forums/threads/3736089/ (sample teams, they portray the metagame quite accurately)
https://www.smogon.com/forums/threads/3724082/ (a ranking that classifies Pokemon based on how viable they are in the format)

I'd also suggest looking up some beginner guides to competitive Pokemon:

If you need any help for competitive related queries you can ask in the Training Academy room for help (https://play.pokemonshowdown.com/traineracademy) or the tier specific room, such as Ubers (https://play.pokemonshowdown.com/ubers) in this case (though not advised because the Ubers room is dead).
