Just launched on the 25th - Star Pirates Infinity might be up your alley: https://play.google.com/store/apps/details?id=com.SHGStudios.StarPirateInfinity
Heavy focus on Sci-Fi, but if you've played a CCG before like MTG or HS, you shouldn't have any problems here!
Hey everyone! Star Pirates Infinity CCG went live on PC and Mobile on April 25th and we're looking for more people to give us feedback how to improve/market the game further. The game is a free to play CCG set in a Sci-Fi setting known as the Star Crash universe. Thanks!
