You know, those red, green, and yellow stars that I see on the back of a Metal Fusion Hasbro product or the number scale bars shown on Burst products and stuff like that. Do they perform as expected in real life? What if I made a beyblade combo according to what has the most red stars/numbers for the attack stat? Would I create the strongest attack type beyblade ever?

Meaningless and useless, it's just marketing
