I saw something on instagram about it having a six color wheel on the back? was that just BS?
It does on the images shown but it seems that was just a mistake. They just grabbed a card back and it happened to be the wrong one. CFB has already stated that it isn't the right back of the card. So, I don't think we should read too much into it.
