Why have the rules changed?
You know why I bought this game? You got it, I did because I wanted to use cards like injection fairy lily (lod-100), yata-garasu (lod-000), etc., those very cool cards of the real game, in the gameboy advance. Unfortunately, rules are now new and very confusing (I don't understand why Konami did this). In this sense the previous game, the eternal duelist, is by far superior. Another good point of this latter game (world wide edition) is that kids that can not read english (yet) from different countries can use it! It is true that Sacred Cards have better and animated grafics but...
