No: open source works because the economy of manufacturing software is so wierd. you can breakdown total costs into development, manufacturing, distribution. Software manufacturing and distribution cost are about as close to zero as you can get. So all it takes is one altruistic soul willing to shoulder the research cost. and there is no reoccurring manufacturing or distribution cost to burden this person. physical trading cards would have a recurring manufacturing and distribution costs. This is, strictly speaking, orthogonal to opensource, an open source trading card by definition would come with the design file used to make the card. I guess you could print your own cards. No: the trading card appeal is scarcity of resource. there is no thrill of acquisition when you can get anything at will. Yes: go to wikipedia and look up information of your favorite sports figures. feel free to put it in a nice template. there is your open source trading card.
