Arceus - 7 Star Pikachu Raid - Solo - Pokemon Scarlet/Violet

Credit to discord user Fly for suggesting using judgment as primary attack rather than giga drain, and for the move sequence.
Arceus @ Meadow Plate
Ability: Multitype
Tera Type: Grass
EVs: 252 HP / 6 Def / 252 SpA
Modest Nature
- Judgment
- Acid Spray
- Calm Mind
- Recover
Vitamins: 25 HP Up (or Health Mochi), 25 Calcium (or Genius Mochi)
Feathers: 2 Health Feathers, 6 Resist Feathers, 2 Genius Feathers
* The last 2 EVs of the 510 total do not affect stats but are included so that the EV diagram in game shows the EVs as maxed
Stats at lvl 100 w/ perfect IVs:
HP : 444
Defense: 277
Sp.Atk.: 372
Sp.Def.: 276
Speed : 276
NPC Advantages: no requirements to win, but arboliva (seed sower) is required in order to KO pikachu on the same turn that arceus terastalizes. gardevoir (life dew), arcanine (flamethrower burn), sylveon (moonblast), toxapex (chilling water), and other intimidators (tauros, staraptor) help. bellibolt is harmful because it can activate lightning rod with discharge, which will raise pikachu's spatk one stage.
Strategy: 4x calm mind, recover if HP gets low. after pikachu resets its stats, 3x acid spray, terastalizing, judgment to victory.
Notes: it's possible to pull off the KO in one tera'd hit without NPC arboliva using attack cheer, or by replacing recover with grassy terrain. if you're worried about def drops from iron tail, you can replace recover with iron defense. if you're worried about paralysis from thunder, you can use covert cloak, but that will lead to far more damage taken from surf before terastalizing, and it will greatly reduce damage output from lack of base grass typing. giga drain can replace recover for healing but must be used carefully so as to not trigger the statwipe at 65% HP prematurely.
Pros: supereffective tera type matching base type, fantatstic HP and spatk stats, great def and spdef stats, outspeed pikachu, resists thunder and surf, calm mind buffs 1 spatk stage and 1 spdef stage. acid spray lowers spdef 2 stages through shield while charging tera orb. recover heals 50% of HP bar, judgment has 100 base power, 100 accuracy, deals supereffective STAB (tera-boosted when terastalized) damage.
Cons: cannot remove pikachu's light ball, vulnerable to paralysis from thunder after rain expires (21% chance) and def debuff from iron tail (15% chance)
Overall Rating: 9/10

[@holographicrue]

does it have to be grass tera to ko with judgement?

[@user-qe6lw7el8g]

Electric might help avoid getting para

[@DaniSoloRaids]

@@user-qe6lw7el8g electric arceus cannot damage pikachu because it has lightning rod

[@DaniSoloRaids]

@@holographicrue yes

[@user-qe6lw7el8g]

@@DaniSoloRaids that’s right, my mistake! Moldbreaker electric type maybe

[@DaniSoloRaids]

@user-qe6lw7el8g there are no mold breaker electric types, but you can make it happen in duos with skill swap and tinkaton as I did in the pikachu mirror match. There's also zekrom's teravolt which has the same effect as mold breaker
