Art is my life Card classes: Collector class, Rare class, Masterclass. Mystery class. Collector class: The most common card class, printed more than once. Rare class: Less common, printed only a few times. Masterclass: One of a kind, special in some way. Collect all the cards in a series to earn a mystery card class. A card that comes coupled with a real physical peice. Happy hunting Warmest regards. ~Koozy This is but the first of many steps towards making my dreams a reality.
