In most card games you are limited to how many copies of a each card you can have in your deck. there are also cards that are limited to just 1 per deck.I think each bakugan should be unique and only allowed 1 per your "team/deck". This could help where the point limit rule may not. By unique i mean that the 3 main elements all match. Attribute, Type, G-power. If one of them is different then it is a seperate bakugan and allowed. Just so you dont have 2 or more bakugan where all 3 elements are the same.( Duplicate ) For instance, you can have a subterra clayf 700g and a subterra clayf 440g, but NOT 2 of the subterra clayf 700g bakugan as they are exact duplicates.Thought or ideas on this rule?
