I recently taped a small piece of paper (by small, I mean about the same shape and size as a normal Facebolt sticker) to a facebolt that hadn't already been stickered. I used a minimal amount of tape, so as to make the bolt function normally. As far as I can tell, the beys both function normally, without any discernible change to the way they spin. Since the facebolt is designed to have stickers on it, would the mod I just described be legal in tournaments?
EDIT: In the future, would glueing a piece of paper to a facebolt also be legal?
