Sounds interesting! How are you thinking on how it should work? There is a lot of rules to follow if the cards is the main focus. What is your idea with the forum? Are people duelists going through competitions or something else?
Personally I have liked watching some of the shows but it hasn't caught my interest in a way of wanting to be a duelist myself. And I don't really have much time for anything else than zz right now ^^'
