Ah, those cards could be removed on the right side of the board, should have been possible to put an infinite amount of it there but I heard there's some bugs where sometimes you can't add more so I'm fixing that. It's just there purely to fit the theme but will update the game to give it some effects. I have an idea on how to indicate the current turn which I may or may not have forgotten to add it into this game, so an update will be made to make it clear to the player hopefully on what's the current state of the game.
Thank you for trying it out!
