>>52434600Timid with Hyper Voice, Psyshock, and then any of CM + Taunt, or CM + MFire /Focus Blast.
You could even use 3 attacks + healing wish and pair her with another wallbreaker / sweeper so you can ideally do some damage early and put them back into shape when gardevoir has run out of usefulness.
In case doubles are your cup of tea, Protect + Hyper Voice + Moonblast + (insert utility move of choice) w/ Modest seems best. idk what spread to use since VGC is weird like that and there are a tonne of possible speed tiers to hit.
