This idea has a lot of potential. If this replaces theme decks i see that having a lot more appeal and value with the 'chase card' on the front. And the play indicator kind of signals to parents and new players that competitive pokemon is a thing that you should think about and potentially branch out into. love it overall
I love the play level idea. Probably not important for experienced or maybe even returning players but for new players and/or parents it's nice to show how strong the deck is. I wish they could explain the different levels in more detail as if it is just play level 1 and nothing else that would be kinda vague.
