I like it, but I don't think it would get used, much. Sort of like the "rich get richer and the poor get poorer" statement someone made. If only the top X people decide it's worth playing(minus the occasional noob who has never been to the forum), then you'll only have X other people that might be on right when you are. Then, as people who aren't as good at PvP start losing upgraded cards faster than they can replace them, they decide it's not worth it, and that number goes down. Then, again, the people who have losing streaks, or who are the new "worst PvPers" lose more cards than they can keep up with. It would just keep going, until there aren't enough people to find a good opponent.
