Just an idea for the development team. Steam (store.steampowered.com) has a user base of millions of gamers who use the steam client to download pc games.
There is a section for free to play games on steam, which I think would help considerably in bringing in new players consistently over time if Battledex were on that list. Many steam users are very frugal and just stick around for the big sales that steam offers, but during times that there aren't many good sales people often go to the free to play section.
From what I hear being available for download from steam can sometimes be difficult as you have to maintain certain standards that valve has set, so it would add a little work to ensure that the game followed all of the guidelines. Still, access to such a huge number of customers might be worth the effort.
Just some food for thought
