hey maybe making strategy guides for each attribute :- just a thought 
Thats a thought..... But there are a very small amount of cards that are attribute specific. Most cards can be used by all attributes. Plus each type of bakugan comes in each attribute so there is no special strategy to relate to one attribute of bakugan that wouldnt work with another. But when i have finished my card pages i will scout out specific cards and see if there are any good strategies that are attribute specific.
