Unless im mistaken there is no way for a user to show off his cards. I mean you can see statistics and such but thats it.
1. I guess what I am saying is maybe te OPTION for an admin to input a small graphical icon when building decks to be used in the postbit, or maybe user profile area....something. Think of how cool/fun it would be to show off your collection, especially when making trades and such. I think it would make for a very fun (and addictive) element to this game.
2.I propose not only that but an in game award system of some kind. Being able to setup awards for tournaments, battles, challenges....etc.
3. Lastly deck icons/preview - it would be nice to have a graphical representation of what it is youre buying. As of right now is the only option simply a link to "buy"?
