Wanna Just Open Packs? Set Boosters Are for You.
Where Draft Boosters are built for Booster Drafts, Set Boosters are built specifically to be fun to open. Each one has an art card, a chance for extra rares, thematically connected commons and uncommons—some even have an interesting card from Magic's history.
If you want to draft, get Draft Boosters. If you want to crack packs just for the thrill of seeing what's inside, get Set Boosters.
One Japanese Alt-Art Card in 50% of Japanese Set Boosters
Each pack contains 12 Japanese-language Magic cards, including 1 Mystical Archive card (Uncommon, Rare, or Mythic Rare), 1 Lesson card (Common, Uncommon, Rare, or Mythic Rare), 1 Rare or Mythic Rare, 1 foil of any rarity, 1 Wild Card of any rarity, 6 assorted Commons or Uncommons that are thematically connected (with Commons connected to other Commons and Uncommons connected to other Uncommons), and 1 Land card—plus 1 Art Card and 1 Ad/Token or special card from Magic's history (a card from "The List").
The Mystical Archive card is a Japanese alt-art variant Mystical Archive card in 50% of boosters. A foil-stamped Signature Art Card replaces the Art Card in 5% of Set Boosters, and a card from The List replaces the Ad/Token in 25% of Set Boosters.
