Probably the best mobile game I've found very similar to poxnora is Cabals Magic and Battle Cards. This game rocks and it supports pc/mac/android/ios and it has cross-platform multiplayer if I'm not mistaken Any others out there close to Pox for mobile that I missed?
I've only been playing it for maybe 6 months but more frequently in last few weeks. It's really polished and it has a good size player base given the game mechanics/complexiity (cross-platform multi-player helps a lot). Great art and the theme of 1930's technology meets the occult is really slick... Definitely worth checking out again. As soon as I played it I kept thinking of Poxnora.
