Magic the Gathering Mystery Booster: Convention Edition Display ★★★★★

Each Mystery Booster: Convention Edition display holds 24 boosters

Each Mystery Booster: Convention Edition booster pack contains fifteen cards: fourteen from the gigantically awesome main set, and one from that "something new and surprising" group of R&D Playtest cards.

With Mystery Booster: Convention Edition's return, there were a few updates made from its initial release.

Two of the Mystery Booster: Convention Edition R&D Playtest cards feature new artwork,  Soulmates and Yawgmoth's Testament

Mystery Booster cards typically include a small printing of the Planeswalker symbol in the lower left corner, similar to what you see in cards from The List found in Set Boosters. While this was the case for all cards in the original printing of Mystery Booster: Convention Edition, in this printing going to WPN stores the Planeswalker symbol will not appear on the Playtest cards. Additionally, there's a known difference in Phantom Centaur in this set. For this card in particular some text is printed black instead of white, including the name, power and toughness, artist credit, and creature type line.

Also, some cards where removed and some got there frequency highten.

But what is Mystery Booster? It's an awesome experience with the feel of a "Chaos Draft" that uses multiple Magic Draft Boosters from different releases but bundles the cards and variety you'd experience into one amazing package. The set itself contains a whopping 1,670 reprints from across the game's history (see below for the full list), plus 121 copies of something new and surprising—R&D Playtest cards you won't find anywhere outside of Mystery Booster: Convention Edition. There are so many cards packed into the possibilities,you could fill an entire eight-person draft and not see the same card twice.

Cards in Mystery Booster have the original set symbols and numbering of one of their printings. The only difference is a Planeswalker symbol in the lower left corner, like what you find on cards from The List in Set Boosters.

Each Mystery Booster: Convention Edition booster pack contains fifteen cards: fourteen from the gigantically awesome main set, and one from that "something new and surprising" group of R&D Playtest cards. You can check out these unique cards on Gatherer and revisit the Mystery BoosterRelease Notes and Gavin Verhey's article about the development of Mystery Booster to learn even more.
