Should add a trading system with other players. Maybe a card gifting system as well. But for a card auto battle game. If you low on time doing some quick battles each day before work is cool. A lot of crazy prices in the shop. Overall the game is. . .alright? But not really it could be way better. Look at warframe they have stuff in the game you can get the premium currency through trading. I know two totally different games. But man. . .
