Good point, I'll add that. I'm glad you like it! By the way, this is all free for anyone to use, so go ahead and print your own decks if you'd like! Mine is coming on Monday, I'm excited to try the physical cards out.
Sorry to hear that! I decided to adapt your rules / ideas and make a rules sheet and cards. I am getting the cards printed soon! I can post them here if you'd like, but I don't want to hijack your thread.
This is the first thing which comes up when googling 'mistborn shelldry'. Did you ever end up making the card or more concrete rules? It seemed like a fantastic start! @Claincy
