So I was thinking of funny set ideas and thought of Specs Deo, and actually the more I thought of it the better it seemed to me.
YourToSlow (Deoxys-Speed) @ Choice Specs
Ability: Pressure
Tera Type: Fighting
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
IVs: 0 Atk
- Psycho Boost
- Psyshock
- Ice Beam
- Focus Blast
So to start off we have a Specs Deo Speed ... wait what do you mean you already know? Are you a mind reader? Anyway both of the Psys let me emit alot of stab damage, as Psycho Boost is the highest base power move and Psyshock let's me hit non Ting-Lu special walls for good damage. And also Ice Beam let's me hit common Grounds and Focus Blast is really crucial coverage alongside Tera Fighting.
Great Neck (Raging Bolt) @ Leftovers
Ability: Protosynthesis
Tera Type: Fairy
EVs: 64 HP / 28 Def / 252 SpA / 164 Spe
Modest Nature
IVs: 20 Atk
- Calm Mind
- Thunderbolt
- Thunderclap
- Draco Meteor
First thing first I figured Meteor for rilla would be better as this lets me more effectively use Deoxys-Speed. The rest is a completely standard set but I still need 3 lines so, Calm Mind is a good set up option. Thunderbolt is an amazing stab option, and Thunderclap is a niche option which lets me bypass it's speed issues.
Furry Bait (Meowscarada) (F) @ Heavy-Duty Boots
Ability: Protean
Shiny: Yes
Tera Type: Dark
EVs: 252 Atk / 4 SpD / 252 Spe
Jolly Nature
- Knock Off
- Flower Trick
- Triple Axel
- U-turn
Next Up is Meowscarada, acting as a good pivot and also letting me have an ever better Dozo ma. Yet again same thing w Bolt, Triple Axel is amazing coverage stab. Knock off and Flower Trick are crucial moves on it. And finally U-Turn is good.
Siren (Primarina) (F) @ Leftovers
Ability: Liquid Voice
Shiny: Yes
Tera Type: Steel
EVs: 252 HP / 244 Def / 8 SpD / 4 Spe
Bold Nature
IVs: 0 Atk
- Calm Mind
- Psychic Noise
- Draining Kiss
- Substitute
Nest up is Prima who I figured could be atleast decent against Moon, while tying into the more offensive theme of the team. same sish here, Sub Calm Mind is a Devious set up combo, Draining Kiss and Psychic noise is a nother really devious combo which denies the opps form healing while letting me heal. And steel is the best defensive type.
OuIncin (Great Tusk) @ Leftovers
Ability: Protosynthesis
Tera Type: Water
EVs: 252 HP / 220 Def / 36 Spe
Impish Nature
- Earthquake
- Stealth Rock
- Knock Off
- Rapid Spin
Tusk is the best Spinner, and provides much needed defense to the team. Also rocks is helpful for Deoxys-Speed. and Knock Off is also appreciated support.
Finally
MegaMind (Slowking-Galar) (F) @ Heavy-Duty Boots
Ability: Regenerator
Shiny: Yes
Tera Type: Water
EVs: 252 HP / 16 Def / 240 SpD
Sassy Nature
IVs: 0 Atk / 0 Spe
- Future Sight
- Chilly Reception
- Sludge Bomb
- Toxic
Gking provides that last bit of defense I needed while also packing Toxic to limit set up and punish bulkier teams. Fs is it's best Move, and Cr is amazing pivoting. Lastly Tera Water is it's best Tera generally.

it checks mons like 
and gets fairy helps it answer mons like band 
. 
I’d suggest keeping it offensive but giving it boots instead. Super power allows it to hit gambit and kill as opposed to missing focus blast. Tera fighting helps you resist sucker punch. 
to support your slower mons like 
and even 
.
