If this was used with bicycle playing cards I’d run a mile to the store to buy it, when I see it on the backs like these, if I’m the spectator, I would think it’s a gimmicked deck, still looks like a great deck,
Both the butterfly deck and the flight deck use an edge marking system. Neither deck originated edge markings and the markings do vary, as do the back designs. Some people will prefer one deck to another, but that's purely based on taste.
