I tried this for a few weeks on and off at release and after rought 6 months periods. Now I revisit it and am pleased to see this burning trash fire down to its last ambers. No discernable human population (0 official facebook likes on the games announcements) and the content updates seem to be an automated system left behind to recycling content and releasing "new" cards with old artwork but higher stats.
It seems SE has long abandoned hope on this game as well, I would not be surprised to find that there is no longer an office at SE for this game (maybe an empty one.) There is virtually zero development done on it in its 4~ years of existance. UI glitches and absent convenience features that existed at release are still in the game.
Final Verdict: You can probably save yourself some phone hd space and time and simulate playing this game by finding a soda machine that eats your quarters and pretend like theres gameplay, because thats roughly what youll be doing if you install this. Putting in money and getting annoyed.
