bassraven, under Additional Equipment Regulations it says, "Product Restrictions: Beyblade Micros, Rip Fire Beyblades, Digital Control Beyblades, the Mugen and Mugen L Drivers, and any Beyblade sideline/promotional product that is not compatible with the mainline Beyblade Burst series of tops are illegal." Any Hasbro or Takara Tomy part that isn't pointed out there is legal in the Burst Standard format, as long as you assemble the Bey correctly. This includes Hasbro's HyperSphere line, although you have to keep in mind that they don't have the home field advantage of the HyperSphere stadiums.
