Each Modern Horizons 2 Set Booster contains 12 Magic cards, 1 Art Card, and 1 token, ad card, or special card from Magic's history (a card from "The List"), with a combination of 1–4 Rares and/or Mythic Rares, 6–10 Uncommon and Commons (max. of 8 may be Common), and 1 Land card.
One non-Art Card of any rarity is a traditional foil. A foil Retro-Frame Fetch Land appears in less than 1% of boosters, and a foil-stamped Signature Art Card replaces the Art Card in 5% of Set Boosters. A card from The List replaces the token/ad card in 25% of Set Boosters.
