Single-Bey MFB Tournament idea

This would be like in the anime, you can only use one bey and use it to be the best blader you can in the tournament. Best out of 5 matches to win a round.

Banned parts would be Zero-G Synchromed combos.
All other parts should be legal as 4D is a fun system and should be allowed to be used. 
Beys with mode changes that require to be taken apart can be changed if the opponent allows it. 

This allows for a challenge of wits, power, and combos to go against eachother. 

Any ideas on how to expand on this concept?
