Mystery Booster 2 is a Magic booster set designed for Chaos Draft, similar to the original Mystery Booster set.[2][3] The set is exclusive to conventions.[4][5] The set contains mostly reprinted cards from earlier sets. Each booster also contains a test card which may be used in draft, but not in constructed play. The set is not Standard-legal. Mystery Booster 2 first became available as part of the Festival in a Box for MagicCon Las Vegas on August 19, 2024.
