Mystery Booster - Booster Pack [Convention Edition] (2019)

Please note that this is the original 2019 Edition available at MagicFests and conventions through 2019 - 2020, beginning at MagicFest Richmond November 2019. The 2019 Edition is identifiable because it has a NOT FOR RESALE label on the back of the back, and does not have a 2021 copyright date.
Each convention-exclusive Mystery Booster pack will contain fifteen cards: fourteen from the gigantically awesome main set (containing 1,694 reprinted cards with a unique Planeswalker symbol in the lower left of the card), and one Research and Development Playtest card. Please keep in mind that all Playtest cards will have the following warning on them: TEST CARD - Not for Constructed Play.
