Streets of New Capenna contains 101 common cards, 80 uncommon cards, 60 rare cards, and 20 mythic rare cards; additionally, many of them appear with alternative treatments, as previously described.

You can find all cards with treatments such as gold, art deco, skyscraper, phyrexian, and borderless in the expansion booster packs, for Draft and Collector Booster, in both foil and non-foil versions. Gold cards are found in expansion booster packs and in Collector Boosters. The embossed foil version of the art deco cards is exclusive to Collector Boosters. Gold cards are always in English, but they can be contained in packs of any language. You can find the Metropolis lands in both foil and non-foil versions in the expansion packs and in draft packs. Each Collector Booster contains a traditional foil Metropolis land.

The expansion booster packs of Streets of New Capenna are the most fun to open: commons and uncommons tell little stories, contain one foil and guaranteed illustrated card, and 30% of the expansion packs contain at least two rare or mythic rare cards.
