If Arceus is hacked into it's "???" form, what type will its Judgment be?

Question

And if Judgement is also ???, then does it gain STAB?

Answer 1

When Arceus is hacked to have its ??? sprite, Judgment will match the type of the Plate it is holding (or Normal if no Plate is held). This is because the Ability Multitype is what changes Arceus' type—the various sprites' recolorings are only aesthetic changes. In other words, because there is no ??? Plate, there cannot be a ??? type Judgment.

??? (Bulbapedia)

Answer 2

It will be ??? type. It will not be resisted or deal super effective damage.
