Mechanic description:
Apart from attack and health values each/some cards can have an extra Good/Evil value that can swing the game to player's favor
Hero will have a "Moral" value that if flipped would make opponent win the game.
Another additional UI improvement would be to track which side is winning per generation. If it's evil UI will look dark, if it's good UI with be more bright.
See if added mechanic would be fun for players.
