[@Xeiyenreisha] No, they don't make you duel better. That is correct. That would be the player-unique cards I'll create later down the line. But that's not the issue here, the issue is that a disk is a status symbol. Having one of the standard three means you're like everyone else, but having a custom disk of some description means you've accomplished at least something of importance. Which is why I don't want Shinrei to have one, as he's still on the same playing field as everyone else even with his BG.
