What I'm suggesting is for there to be either an external move, to have it switch over to Shields Down form, similar to how you can mega evolve outside of battle. Or, something more in the nature of Hoopa's prison bottle, having Minior change form upon being right-clicked with said item in hand. All of this would be purely cosmetic, of course, all in the same vain as how megas work outside of battle, reverting to it's base form upon entering a fight.
