Wizards of the Coast has officially launched Mood Swings, a brand-new prototype trading card game from Magic: The Gathering Head Designer Mark Rosewater, and the pitch is instantly intriguing. This is not another Magic variant or a deckbuilding-heavy side experiment. It is a faster, lighter, more accessible card game built for two to four players, with 5 to 10 minute matches and no deckbuilding required. After living in Rosewater’s head for nearly 30 years, Mood Swings is now available worldwide exclusively through Secret Lair, which makes this one of the more unusual and personal releases Wizards has put into the world in a long time.
A Trading Card Game Built for Speed and Variety
The strongest thing about Mood Swings is how clearly it knows what it wants to be. Rosewater calls it his love letter to trading card games, but instead of asking players to study metas, build decks, or learn a mountain of rules, the game seems focused on quick sessions and immediate play. Each deckbox includes 45 randomized game cards, plus a rules card and play aide, which means players can crack open a box and start playing right away.
That makes the game feel designed for flexibility. Each round, every player drops a card, totals are compared, and the highest score wins the round. Win three rounds and you win the game. But the hook is that the cards represent moods and emotions, and those effects can change the playing field and even shift the rules as the game goes. That gives Mood Swings a little unpredictability without sounding intimidating.
Mark Rosewater’s Side Project Finally Becomes Real
There is also something genuinely cool about this release because it is so tied to Rosewater himself. He says the game has been part of his life for almost three decades, which gives Mood Swings a very different energy than a standard product launch. It sounds less like a brand extension and more like a designer finally getting to put a long-running personal project in fans’ hands.

The game also seems built to scale around different kinds of players. Rosewater specifically points to a team format he shared with a family, where each parent could pair with one child. That is a smart little detail because it shows Mood Swings is not only chasing traditional TCG fans. It wants to be approachable for newcomers, casual groups, and people who may never have touched a card game before.
Secret Lair Gets a Brand-New Game


Wizards is offering Mood Swings – 1st Edition for $24.99, which includes one deckbox with 45 randomized cards. There is also a Mood Swings Emotional Support Bundle for $124.95, which comes with five deckboxes. The whole release is available only through MagicSecretLair.com.
