Though I think it'd be likely that people would mega evolve immediately.
There are un-stealable items however, like Giratina w/Griseous Orb, and Arceus holding a Plate.
It'd more likely be like those. --- A voice of reason, in a chaotic realm. "Are you angry? Do you hate me?"

Or switcheroo to stop something like Mega Mawile from getting a prolonged chance to use that godly attack stat by forcing them to revert. --- Where did you come from? Where do you go? Where did you come from, demon-eyed Jho?

You already can't steal items that cause forme changes. I don't see why Mega Stones would be treated differently. --- Creator of Jay's Journey (see quote!) "It's not ten years old! Therefore, it sucks!" - Nostalgia whores everywhere

If mega evolution doesn't have priority then I guess it would be possible unless the mega stones are like arceus plates or giratina's orb. --- 3DS FC- 2981-5785-3794 Pokemon white 2 FC-2838-7906-7636
