This is a Magic: The Gathering Mystery Booster Booster Box, Convention Edition (2021 printing), brand new and factory sealed in its original shrink wrap as released by Wizards of the Coast. The box is unopened and holds 24 sealed booster packs. Any flaw in the seal or packaging is shown in the photos. It ships carefully packed and protected.
What happens when Magic's designers raid their own vault? Mystery Booster was the answer: a draft product drawn from a list of 1,694 cards spanning decades of Magic history, built so that no two packs, and no two draft tables, ever play out the same way.
Every reprint carries its original expansion symbol plus a small white planeswalker mark in the lower left, so you might crack a classic Mirage-era common sitting next to a Modern-era staple. The Convention Edition adds the real conversation piece. In place of the Retail Edition's foil slot, each pack holds one of 121 playtest cards: black-and-white, sticker-style designs straight out of R&D experimentation, full of wild mechanics and inside jokes that were never meant for tournament play. They are not legal in Constructed, but they are pure joy in a Chaos Draft.
The original Convention Edition first appeared at MagicFest events in late 2019. This 2021 printing went out to WPN game stores in a limited run, with a couple of playtest cards receiving new art and adjustments to the reprint list. A full box is a ready-made draft night for a big group, or a long, rewarding solo crack through Magic's back catalog. Few products capture the playful side of the game this well.
