The set didn't have a limited print run and the availability of themes wouldn't change, though it was put on hold during the 2019-2020 coronavirus pandemic. Jumpstart was also available in the Jumpstart Multipack, which includes four 20-card booster packs. The booster pack itself is wrapped like a regular pack, but the set of cards is packed in an additional plastic wrap, with a face card (the "Pack Summary card") that indicates the theme and the color of the half-deck. The planeswalker-themed packs use their respective Showcase lands from M21, but the other packs use brand-new art created specifically for this set. Within each pack, seven or eight of the 20 cards are lands and the rest are spells one basic land in each pack (or in the case of the Rainbow theme, Terramorphic Expanse) features art that matches the pack's theme. All boosters contain at least one rare, and one in three boosters includes an extra rare. Most themes are mono-color, and all themes, with the exception of mythic rare themes, have multiple variations of cards included in the pack, with (usually) each card appearing only once in a pack the set has a total of 121 different pack contents. The contents of each pack fit a randomly-chosen theme, with each theme having a "rarity" of common, uncommon, rare or mythic rare. Jumpstart was primarily sold in 20-card boosters, with 24 boosters per booster box. The set was designed for two-player gameplay, but players can also play multiplayer with it. The other reprints with the Jumpstart expansion symbol are numbered #79-495 (186 commons, 147 uncommons, 73 rares, 11 mythic rares). The new cards and cards with new art are numbered #1/78 to #78/78 (11 commons, 7 uncommons, 14 rares, 6 mythic rares, 40 basic lands). 169 cards are from Core Set 2021 and feature the M21 expansion symbol, and over 400 are reprints from sets before Core Set 2021, which, along with the new cards, have the Jumpstart symbol. These are not Standard-, Pioneer-, or Modern- legal cards, but they are legal in Eternal formats (Legacy, Vintage, Pauper and Commander). The set contains almost 500 reprints but also introduced 37 new cards that were designed to help fill out some of the themes. To play a game of Jumpstart, players simply open two boosters and shuffle them together to form a ready-to-play deck. The set introduced a new way to play Magic that mashes together themes from throughout the history of the game and lets you skip the deckbuilding part. In this, it is similar to the Smash Up game by Alderac Entertainment Group and KeyForge by Richard Garfield.
Jumpstart melds an easy way of deckbuilding with the “ shuffle up and play” speed of constructed.
