I hate how Takara Tomy wants these to be exclusive Beyblades but then wants to make the game into a global sport, which, let's be honest, it will never be a global sport if this is how they want to gatekeep stuff.
A solution for this is to give the Hasbro side non-painted versions to make the game fair, and if Takara Tomy refuses, then the next time Hasbro makes an exclusive Bey that's competitive like Hover Wyvern they shouldn't let Takara Tomy release their own variant even as an app prize.
Another solution would be to have both the current Hasbro Beyblade app and an app that only those who are legal gambling age can have access to, I only know American laws, so that would be 21+ and you have to send a picture of your driver's license or state ID or a passport to verify your age. This version should be able to use all codes that are already out, and then the Hasbro products start to come with a QR code themselves.
