Each box of Set Boosters will be accompanied by the Innistrad Crimson Vow Buy-a-Box promo (while supplies last).
Each Set Booster comes with a guaranteed rare or mythic rare card and more—a foil card, beautiful art card, thematic commons and uncommons, plus a chance at a card from The List—making it exciting to open and add to any Magic player's collection.

Each Set Booster Box contains 30 Set Boosters
(Set Booster Early Release Canceled: Due do production and shipping delays, Set Boosters will not be available for Early Release during Innistrad: Crimson Vow Prerelease. All other Early Release items will be available as expected.)
