Here is what intrigues me: We know from the pack arts that Japan's next SuMo Set will feature Ho-oh and Necrozma, so I wonder if Necrozma will be a part of the movie at all, and if the set will have Marshadow in it. Just thinking out loud here, but in order to get a rainbow, you need a prism. Necrozma anyone?
