I am waiting for the mobile version of Gods Unchained. Currently there is no mobile version, but the developers are already working on it. Nowadays I do not have a PC/laptop. This is the only reason why I still have not tried this game so far, otherwise I would already play it.
Good luck and have fun.
They have planned mobile release at the end of the year if I remember correctly. But if you are sure that you want to play on mobile, you could grab some cards now while they are cheap. The sale of the latest expansion is still running.
