Query: A must for any serious Pokemon trader

I bought this video for my son who can never get enough Pokemon stuff. He is especially interested in the trading cards, so these videos seemed to fit his needs perfectly. we were not disappointed! Not only is the video very informative, it is fun to watch. There are a few celebrity kids playing in a tournament and explaining their strategies. My son has learned so much from watching these tapes over and over. We think you will too, and given the low price we think it should owned by all Pokemon card traders.
