It's not illegal as in Country Laws, it's illegal as in "You can not use this customization in Official Beyblade Tournaments". Hasbro/TakaraTomy did not make the Perseus Clear-Wheel to fit on the Meteo Metal-Wheel, it was only an error, so they do not want you to use them in their tournaments. That's all. Don't get so pissed about a simple question...
