So am a not so much a new collector but a returning one (used to collect when younger but gave them all up long ago... sad face now...).
Set my goal on Celestial Storm because well it has Scizor GX which has been my fave mon pretty much since I ever discovered it. So theres 183/168 cards avaliable but on the side theres also pretty much a similar amount of Reverse Holo also and various Promo cards.
To me am guessing the "full" collection for a true collector would be EVERY possible card from the set, but whats others opinions? Would you got for just 183 cards (mixture of Reverse Holo and plain etc) or would the true collector have to collect the full lot....
