From the Publisher:

Each Prerelease Pack is themed around one of Strixhaven’s five colleges. Each Prerelease Pack contains the following:

• 5 Secrets of Strixhaven Play Boosters
• 1 Secrets of Strixhaven college-themed booster
  • Each college-themed booster contains cards from among the college’s two colors.
• 1 Traditional foil promo card
• 1 Deck box
• 1 Spindown die (matches the Prerelease Pack’s college)

You’ll assemble a 40-card sealed deck using the contents of your Prerelease Pack and any number of basic lands. Then, you’ll engage in some friendly debate and play against your fellow Prerelease attendees. Prereleases are casual, relaxed events, so don’t be afraid to ask questions and test out new strategies!
