IDK really, I just got a cool 6IV naive one, any plate will do haha
Ok. What makes for a good mixed Arceus.....
The only ones I can think of are Rock Arceus, Ground Arceus, and Ghost Arceus. Because Judgment is specially based and is the same type as the plate it holds, Rock and Ground Arceus can pack a special based Rock and Ground attack, which is pretty rare (those types are often physically based). So for them, you could try something like this:
-Arceus w/Stone Plate
Nature: Naive
Ability: Multitype
EVs: 252 Attack, 252 Speed, 4 Sp.Attack
Moves: Judgment, Earthquake, Calm Mind, Recover/Refresh/Extreme Speed
-Arceus w/Earth Plate
Nature: Naive
Ability: Multitype
EVs: 252 Attack, 252 Speed, 4 Sp.Attack
Moves: Judgment, Stone Edge, Calm Mind, Recover/Refresh/Extreme Speed
These 2 basically act the same, just with the Ground and Rock attacks physical/special being swapped. The nice thing about these is that it gives Arceus good mixed offenses since it has the Attack EVs but can boost its Sp.Attack with Calm Mind, which also gives it more resistance to the Water and Grass attacks they don't like, while posing as a common Calm Mind Arceus which may trick your opponent into switching in a special wall that will get promptly killed by the physical attack. Ground and Rock also get fantastic (netural) coverage together.
Oh these sound so good, I wanna try them out on Showdown....
Ghost gets good coverage by itself since Game Freak thought it was a good idea to remove Steel's resistance to Ghost, so try this for Ghost Arceus:
-Arceus w/Spooky Plate
Nature: Naïve
Ability: Multitype
EVs: 252 Attack, 252 Speed, 4 Sp.Attack
Moves: Shadow Force/Shadow Claw, Judgment, Brick Break/Focus Blast, Calm Mind
or
-Arceus w/Spooky Plate
Nature: Naïve
Ability: Multitype
EVs: 252 Sp.Attack, 252 Speed, 4 Attack
Moves: Shadow Force/Shadow Claw, Judgment, Brick Break/Focus Blast, Swords Dance
Like the sets for Rock and Ground Arceus, you can probably trick your opponent into thinking that Arceus is just physical or just special based (because 99.9% of all Arceus's are like that) when really its mixed. Set up and blast away!
Whatcha all think of that?
