Hi all! I'm just beginning collecting Pokemon cards with my son, and I'm currently gathering information. Could someone please tell me, do cards in theme decks have their own numbering system, or do they have the same numbers as the cards released in the corresponding booster packs? I ask this because I have found out that some theme decks have exclusive cards, and now I'm a little confused as to how it works! I'd appreciate someone explaining it to me please! Thanks!
