witch type of beystaduim is tournament legal in the WBO in Ohio DIY or hasbro

DIY Staduims are pretty good but they are aganst The rules of the WBBA
hasbro staduims are the real deal but are they against the WBO rules in ohio
Exactly: the first kind cannot be regulated and normalised, therefore they are illegal, and the second type of stadiums is unfair to some or all Beyblade combinations.

I therefore do not really understand your question: that leaves TAKARA-TOMY stadiums as being legal. It does mean that you would have to import one, but they are still relatively cheap and we all had to import ours, no matter where we live. If you need any help with that, you can check the stickied topics inside the Bey Marketplace forum.
