That would suck because not everybody would have access to the cards needed to make a deck good enough to win... therefore, upper class people stay upper class because they win games because they have good cards, whereas lower class people stay lower class because they lose games because they can't afford good cards. Also, how well you do in a card game has absolutely nothing to do with what you're like as a person, and everything to do with luck and ability at that specific game. Someone could be a musical genius, but suck at cards, and would lose all the time.
