Upper Deck's Legendary: A Marvel Deck Building Game Second Edition released June 17, 2026, as a full rebuild of the 2013 Core Set rather than a simple reprint.
The headline change for anyone actually unboxing it isn't a new Mastermind or a reworked Scheme, it's the sheer volume of cards now sitting in one core box.
550 playable cards is a meaningfully bigger storage project than the original 500-card Core Set ever was, and the included 60 dividers and playmat change how that storage should actually be organized.
Here's exactly what ships in the box, the real card size and count, and how to sleeve and store it correctly from the first game night rather than retrofitting a system later.
Second Edition ships with 550 playable cards, 60 dividers, one rulebook, one keyword reference guide, and one playmat, confirmed on Upper Deck's own product page and ICv2's coverage of the set. That's up from the original Core Set's 500 cards, with 250 of the returning cards redeveloped and 42 dedicated Bystander cards included.
New content in this edition includes Doctor Octopus as a playable Mastermind, the Sinister Syndicate as a new Villain Group, a ninth Scheme, and Spider-Man in his Miles Morales identity taking the Deadpool hero slot from the original Core Set.
Legendary's card stock stays at the standard poker footprint, roughly 63.5mm by 89mm, the same size used across the original Core Set and every Legendary expansion to date. That consistency matters for a deck-building game like this one, since Heroes, Villains, and Schemes all shuffle together into shared piles during setup.
EVORETRO's Matte Card Sleeves Standard Size fit the entire 550-card set without needing a different sleeve for any individual card type, which simplifies what would otherwise be a fairly intimidating sleeving job.
Second Edition's 60 included dividers are a genuine upgrade over the original Core Set, which shipped without a built-in sorting system at all. Those dividers are meant to separate Heroes, Villains, Henchmen, Schemes, and the new Bystander cards directly inside the box.
Using the included dividers as the first layer of organization, rather than buying a separate divider product, is the right call here, since Upper Deck already solved that specific problem for this release.
A 100-card deck-builder like Dominion is a weekend sleeving project; 550 cards is a different scale of task entirely, especially once double-sided Mastermind cards and the new Bystander subset are factored in. Doctor Octopus and every other Mastermind in this edition print on double-sided cards, offering a standard and a harder difficulty mode on the same physical card.
Sleeving a double-sided card works exactly the same as sleeving any other standard-size card, but it's worth sleeving these specific cards early, since they get handled and flipped more often than a typical Hero card does across a campaign.
Once sleeved, 550 cards no longer fit comfortably back inside the original box alongside the playmat and dividers, which is the point where most buyers underestimate how much storage this release actually needs. A dedicated bulk card box built for several hundred sleeved cards is a more realistic long-term home than the game's own insert.
EVORETRO's Magnetic Card Deck Storage Box, built to hold up to 1,800 cards, comfortably handles the full 550-card set with room left over for future expansions, which this franchise reliably gets.
Legendary's expansion-heavy release history means Second Edition's card pool is realistically a starting point, not a finished collection, and storage decisions made now should account for that growth. Our Deck-Building Games vs. Living Card Games explainer covers how this genre's expansion model differs from an LCG's, which is useful context before committing to a storage system sized only for today's box contents.
Buying one bulk storage box sized for growth up front avoids a second storage purchase six months from now once the first expansion lands.
Second Edition isn't just a bigger pile of the same cards, every returning Hero now uses four different pieces of artwork across its four printed copies instead of repeating one image, and Mastermind cards in particular were redesigned from the ground up to support the new double-sided difficulty system. That redesign work is part of why 250 of the returning cards needed full redevelopment rather than a simple reprint.
Knowing that the artwork and card design genuinely changed, not just the quantity, is useful context before assuming a First Edition sleeve or storage habit automatically carries over unchanged to this release.
