In the case of Pokemon or MTG, it's very important that the back of the cards look the same across the years and generations, so that the opponent can't see what the other player is playing. Of course, with MTG people often use card sleeves so it's a bit moot.
Writing the name of the card you want it to be in sharpie on the front of a real (but cheap) card trivially solves this problem for cases where card sleeves are not in use.
