Fans of the collectible card game Magic: The Gathering are getting a new expansion set in August. Magic publisher Wizards of the Coast, which is a unit of global toy giant Hasbro (NASDAQ: HAS), announced the "Double Masters" set on Thursday, May 21. What's new? Fifteen-card booster packs will hit the Magic Online e-commerce site on Aug. 6. The full Double Masters set of 332 cards will hit store shelves and online retail channels on Aug. 7, packaged in 15-card packs and 24-card booster boxes. The key word here is "Double." Wizards made sure to double the number of rare cards per booster pack, the number of foil cards per pack, the number of box toppers, and more. The popular Doubling Season card, for example, shows up in its standard form and a reimagined box-topper version with the same rules but new art. This is the fifth Magic set to feature the rare Doubling Season card. Image source: Wizards of the Coast. Wizards will hold an unveiling event at 5:30 p.m. EDT today on Twitch, revealing four more Double Masters cards. A larger preview event will follow in July, displaying the entire set of 332 cards. This set is part of Wizards' rolling release schedule for new Magic content. The game has become a significant driver of Hasbro's quarterly revenue through a combination of competitive events and online gaming platforms. Hasbro doesn't break out individual games in its quarterly earnings reports, but Magic is a key part of the company's gaming division, where revenue grew 40% year over year in the quarter that ended on March 29, 2020. 10 stocks we like better than HasbroWhen investing geniuses David and Tom Gardner have a stock tip, it can pay to listen.
