With the emergence with Highlander Gauntlet; it’d be nifty to be able to record and track your 6 decks automatically. As a modification of a normal folder, a “Gauntlet Folder” would track all cards within; between each deck. Flagging shared cards allowing the user to easily organize and track what changes are necessary. I feel like it’d utilize similar flagging like the Game Changers and other deck construction limits already in use. I understand it’s very niche, but just an idea I believe both seasoned players and beginning Highlanders would appeal to.
