Core 2021 features a mix of new and reprinted cards. The set contains 274 cards.
In the classic Magic booster pack there are: 10 commons, 3 uncommons, 1 rare or mythic rare, 1 land, and 1 token/ad card. Around a third of the time, one of the commons will be replaced by a foil of any rarity. It's also possible that you get a card in a showcase frame, an exciting alternate version of a normal M21 card.
Contents: • 36 packs per booster display • 15 randomly inserted cards per booster pack
