Speaking of anti-Imposter Proteans, I might as well share a set I've been using:
Mewtwo-Mega-Y @ Spooky Plate
Ability: Protean
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Judgment
- Boomburst
- King's Shield
- Secret Sword
If Chansey switches in while you are ghost-type, you can just spam Judgment and they can't hurt you at all; even if they use Boomburst to become immune to Judge, they only have 5 pp. And even if they come in while you aren't ghost-type, you can anti-imposter this with literally any ghost-type; try running set-up moves on the ghost-type to take advantage of the free turns you get. Ghost/Fighting is phenomenal coverage, hitting everything in the tier for at least neutral damage, and getting super-effective damage on a lot of notable Pokemon, like Giratina, both Mewtwos, and steel-types. Boomburst hits neutral mons harder than anything else on the set, but it's not really necessary, and you might want to replace it with something else, like a set-up move or recovery.
