One of the most intriguing reveals at MagicCon Las Vegas 2026 had nothing to do with multiverse-shattering narratives or superhero crossovers. It centered on a project previously shrouded in secrecy: Secret Lair Presents: [REDACTED] with Mark Rosewater, led by Magic: The Gathering’s chief designer.
Following a cryptic tease on his personal blog back in February, Rosewater finally pulled back the curtain. The mysterious project is Mood Swings—an innovative, decades-long passion project that aims to redefine the boundaries of the trading card game (TCG) genre.
At a glance, it might be tempting to categorize Mood Swings as a simplified “Magic-lite” experience, but that does a disservice to its core objective. Rosewater created this title to tackle a major barrier to entry for newcomers: the sheer intimidation factor. Between the daunting depth of mechanics and the necessity of navigating massive card pools, starting a TCG can feel like an insurmountable hurdle for beginners.
“Magic is a complicated game,” Rosewater explained during the preview. “I have family members who will never play it. I wanted to design a trading card game that feels truly accessible to everyone.”

Designed for two to four players, matches typically clock in at under 10 minutes. Each 45-card deck is drawn from a curated 133-card pool, featuring a specific distribution of common, uncommon, rare, and mythic rare cards to ensure balance.
“If you buy the same game as your friend, you expect it to be identical,” Rosewater noted. “But with this, we’re playing with the idea of what happens when your version and mine are distinct.”
While the decks are perfectly playable right out of the box, players who enjoy customization can swap cards of equal rarity to experiment with different strategies—though it remains entirely optional. The goal, ultimately, is to create a game that a player can intuitively understand after just one match.
Gameplay is snappy and intuitive. Players start with five cards and take turns playing “Mood” cards—such as Joy, Rage, or Ambition. The player with the highest score takes the round, and cards remain on the table, building a narrative across multiple rounds. Securing three wins ends the game. Much like Magic, these “Moods” feature unique abilities, such as the Ambition card, which allows players to discard from their hand to play an extra card—a high-stakes maneuver that can clinch a win but leave one’s defense vulnerable.
In pacing and scope, the game shares the DNA of classic card games like War, infused with just enough strategic depth to keep things interesting. While enthusiasts can certainly deep-dive into the card pool to optimize their play, the game is balanced enough that no base deck ever feels strictly superior.
Rosewater has been nursing this concept since 1998, spending nearly 30 years refining the idea. His journey is the subject of several panels at this weekend’s event. The project finally found its home through the Wizards of the Coast Secret Lair team, known for championing experimental releases. The game features sketch-style artwork sourced from existing Magic illustrations, giving the entire set a raw, behind-the-scenes aesthetic.
“I wanted something universal,” Rosewater explained. Inspired by his background in theater and his mother’s work in psychology, he decided to theme the cards around human emotions. “We all relate to emotions; that’s a language everyone speaks.”
Mood Swings represents a thought-provoking challenge to the complexity of the current market. Whether it finds its audience remains to be seen, but the first edition launches June 1 as a Secret Lair exclusive, retailing for $24.99. While future expansions hinge on the game’s commercial success, Rosewater remains optimistic.
“I’ve always believed in this concept,” he said. “I never stopped trying to bring it to life.”
