Unfortunately I believe this places the nail in the coffin as for the usefulness of magician.Magician will also not activate if the user hits the target with an attack on the same turn it consumes its held item, in this case Braixen consumed Normal Gem using Return and hit Florges holding Pixie Plate and Magician did not activate.
On a happier note however,
Wish gives Delphox a way to differentiate itself a little with a fast wish. I honestly don't know how effective it will be with only average bulk but at the very least it has the option.fennekin can learn wish (deseo) for move egg with smeargle, so somewhere can learn psychic/fire move to smeargle
