I know they're only in the Concept stage of CAP 21, but I have a question:
Whenever CAP 21's Art Submissions arrive, is it okay to design a "Mega Stone" for the CAP whose design is more than just a palette swap of the glass marbles in XY and ORAS? Just for flavor, of course. If you approve of the idea, I'll surprise you with what I've learned from Smeargle's Studio.
