Hoopa and Volcanion are more likely. But Mega forms? Nah, Remember when they removed the form code for Meloetta-P and Zen mode Darmanitian because it causes some problem when brought to amie. Well, I never tried bringing my permanent Megas to the Amie and will never do lol but I am pretty sure they will cause the same problem as Meloetta-P and Zen mode Darmanitan.Now, all that they need is Hoopa, Volcanion, and Mega Form select.
