@BG: The collectible/trading aspect is simply there to make the creators money, from my perspective. It adds nothing to the game. Our most popular gametype among my friends is a draft played on lackey. Free, and the exact same gameplay. The only downside is you don't win awesome cards at the end for use in constructed play :P.
You're right though that the interface is 'rinky dinky'. It's very functional after a game getting used to it, but it could stand to be web 2.0'd :P
