My son is 8 the kids in school are getting in to pokemon card games now and he wants to also but getting clear straight answers from 8 year olds isn't always easy.. can someone please tell me what the current pokemon cards are to buy a starter pack/deck and especially packs to open?..he'll enjoy that most..and a resource if there is one out there for what is good better best so we can check out his cards together as he learns how to play and also how to not get burned trading?
