I was thinking about this, and ill share with you the idea:
Banding 6 cards, cards are 6/5, so the total is 36/30, feels very undefeatable. All i believe you can do is try to either jump up in strength and/or try to remove as many as you can. So i was wondering, is there a limit to this to prevent some great chain that allows you to get to 50/50?
