At its foundation, Jumpstart is simple. Grab two boosters, shuffle them together, and you're ready to go. But a closer look reveals an intricate play experience unlike anything in Magic.

It works like this. Each Jumpstart booster includes 20 cards. All 20 cards fit a theme, and most themes have multiple variations—enough to make 121 possible 20-card lists inside any given pack.

Themes range from the familiar ("Garruk") to the curious ("Doctor"), and two themes sometimes come together to form an unlikely mishmash ("Doctor Garruk"). If you've ever wanted to make a Cat Pirate deck well, meow is the time. There are even special "Mythic Rare" packs that don't have variations at all—just the one card list—because there is only one true Unicorn deck.

Jumpstart is different than anything we've done before, so here are some key things to know about this product releasing on July 17.

• Each booster contains 20 cards centered on a theme. What theme each booster contains is randomized, but each themed 20 cards will be sealed inside the pack and labeled. 
• One in three boosters includes an extra rare.
• It's loaded with reprints—almost 500!
• Jumpstart introduces 37 new cards to the game. These will not be Standard-, Pioneer-, or Modern-legal cards. They are legal in Legacy, Vintage, and Commander.
• It's closely tied to Core Set 2021—they share a lot of content and release near one another—but Jumpstart is a stand-alone product.
• All cards are legal in Eternal formats (Legacy, Vintage, and Commander)
• Every pack includes one basic land with art that matches the pack's theme. A few of them use thematically appropriate lands from M21, but most of them use brand-new themed land art created for Jumpstart.
