I've seen some of you post your lovely promo cards here and some are just pictures of the cards but some come wrapped in plastic with some sort of booklet.
So what I'm asking is how do I find out which cards are released for what occasion, and what cards there are to collect? How should they be packaged (with the booklet?) so I know what I'm looking for and I'm guessing the prices depend on the Pokemon, as with normal TCG cards. Are they all in Japanese and what's the booklet for?
