I have played a version of it with actual cards and I was having a ton of fun inventing the rules and stuff, but to actually put it in the game would take more programming knowledge than I have, but in the future I do actually want it to be a playable minigame because it's very fun... I just hope I remember the rules... I don't know if I explained them in enough detail in that emma event and it's been almost a year since.
Also you are the first person to mention Emma's Ultra Hand and I am so happy someone finally wants to play it lmao.
