So I recently started playing pokemon online and have loved playing it, and was wanting to buy real packs and play at some locals in the near future. I was wondering what packs should/can I buy that are allowed in the tournies amd how often do they come out with new packs? And How do I know when the packs/cards are to old to use in tournys? And what packs that are out in stores that are to old to use in tournys?
