Each Mystery Booster - Convention Edition booster box contains 24 packs from the main Mystery Booster set, plus one extra-special "R&D" card. You won't believe the stuff they came up with! Mystery Booster: Convention Edition is designed to emulate a Chaos Draft as it contains more cards than any Magic set ever at 1,670 reprinted cards. In addition, each pack contains 1 of 121 different playtest cards that are exclusive to Mystery Booster: Convention Edition. Please note that the list of possible cards as well as the art from two playtest cards have been altered from the original 2019 release.
Unlike customary reprints, Mystery Booster cards are presented in their original form - original frame, art, typesetting, expansion symbol, legal text, and all.
Look for these great cards:
