The Strixhaven: School of Mages Prerelease Packs are slightly different than more recent set packs, and bear a similarity to what they once did with guilds in the Ravnica sets (see " 'Magic: The Gathering Ravnica Allegiance' Products and Dates"). Instead of guilds, these packs are centered around the five colleges (see " Wizards of the Coast Releases Initial Product Details on 'Magic: The Gathering' 'Strixhaven: School of Mages'") with one of the six boosters being a College Booster. Each pack comes with 5 Strixhaven: School of Mages Draft Boosters, a Strixhaven: School of Mages College Booster, a foil promo-stamped R/M card from Strixhaven: School of Mages, a MTG Arena code card (in select regions), and a Spindown life counter. These cases will also come in cartons of 20 packs instead of the usual 18.
