Jumpstart is a new way to play Magic that mashes together themes from throughout the history of the game and lets you skip the deckbuilding part. Grab two boosters, shuffle them into a 40-card deck, and start playing. The set contains almost 500 reprints but also introduces 37 new cards that were designed to help fill out some of the themes. These are not going to be Standard-, Pioneer-, or Modern-legal cards, but are legal in Eternal formats (Legacy, Vintage, Pauper and Commander). There are no foil cards in the set. 120 cards are from Core Set 2021, and more than 400 reprints are from sets before Core Set 2021. Cards from M21 have the M21 expansion symbol, while new cards and other reprints will have the Jumpstart symbol. Reprints have a Post-M15 card frame. The new cards and cards with new art are numbered #1/78 to #78/78 (40 basic lands, 11 common, 7 uncommon, 14 rare, and 6 mythic rare). The other reprints with the Jumpstart expansion symbol are numbered #79-495 (186 common, 147 uncommon, 73 rare, 11 mythic rare).
The set was designed as a two-player game, but you can also play multiplayer with it.
