These premium packs have the same number of cards as normal boosters, however, while normal booster packs have a single foil card and only a chance of containing a Hyperspace or Showcase variant, all cards in a Carbonite pack have some form of special aesthetic treatment. This means that when you open up a Carbonite Edition booster pack, every single card is guaranteed to be a collector's item, whether it's foil, Hyperspace, Hyperspace foil, Showcase, or the new, Carbonite Edition-exclusive Prestige variants. That said, as a quick emphasis, these are all variants of existing cards in the set - no unique cards will ever be exclusive to Carbonite Edition packs, just unique aesthetic treatments.
Each booster pack contains 16 cards
