Yu-Gi-Oh! TRADING CARD GAME tournaments can be run in two formats, Traditional and Advanced. The Advanced Format utilizes a Forbidden List of cards that you cannot use in your Deck. Not using these cards makes the game more intense and exciting. Plus all the big tournaments around the world use the Advanced Format, so if you are inspiring to be a World Champion, be sure to practice this format.
Even when just playing with your friends you should be sure to agree if you are playing Traditional or Advanced format, that way the game is fair. You wouldn't want to be the only one caught using a Traditional Format Deck if everyone else is playing Advanced Format!
