Yes, at the moment we have a complete random, but we plan to make a full-fledged calode of cards, so that you can collect it yourself and know what kind of cards there are and how many of them. Thank you very much for your comment!
As a game dev, this is very possible, but I personally think it would be more interesting to make the player make conscious choices about how to build their deck. Look towards other roguelike deck builders (slay the spire, cough cough) on how to execute this well. But this is an awesome foundation and I really do hope Amsern Studio keeps developing this, I'd gladly pay money for a more expansive and polished version of this. Awesome!
