I ran a review of this game a few years back on WebcomicZ: WAGON Webcomic Battle Review. It was less than favorable, but optimistic and (I'd like to think supportive of the concept).

I see they're still around and kicking and working on Version 2.0. Here's hoping they succeed. If not... I may just have to give the concept a run myself as I have plenty of ideas for making a fun and easy to play Webcomic-based card game. We'll see.
