The devs are active with their players on a daily basis, something I have not seen in over 400+ games. As far as the game goes, its ftp friendly for the most part. Solo campaign lets you craft any card the user desires in a matter of days. Runs on the cheapest devices, doesnt drain a lot of power. Some champs are more powerful than others but alas balance is always a looming issue with CCGs. There is a mercy counter for epic/legendary cards.
