So, I noticed that the cards are market board forbidden and also unsellable to regular vendors, but what about trading them to other players? Game doesn't say they're untradeable. This probably won't work as well as I'd hope it would, but I'm already an avid TCG player I do like the idea of trading or selling cards to other players. Then again, given the fact that you can sell them for MGP, this probably won't be a well-received or well-thought-out idea or someone else would have come up with it by now.
