User crafting of new cards

This idea is about introducing crafting to TrophyRoom! Whut? Yes! Let’s imagine for a sec that each card consists of a number of “stats” or “elements” that you gather by winning challenges or completing achievements. Once you have gathered enough of these elements, you can craft a any card for which you have enough of these elements. These cards can then either be used in the game or sold by the players themselves via the shop!
