correct me if i'm wrong but was au not allot more affordable for card flipping than the new token system? i'm a noob who has only been playing for a month now and i'm only able to reach gold rank after much gameplay which gets me barely enough tokens to do anything with. I was at least able to earn about 100 au a day from daily missions and battles which i would then save up for the robot or weapon i wanted from card flip and i was quite satisfied with that.
