The developers of the game without warning announced the release of Jumpstart: Historic Horizons . It is to contain as many as 782 cards, including 372 previously unavailable, which will be available only in the Internet space. A major update will be needed to bring the expansion pack to the game, so Wizards of the Coast have decided to delay the release of Jumpstart: Historic Horizons .
We’re shifting everything by two weeks. The premiere, scheduled for August 10, is postponed to August 24, and the release of Jumpstart: Historic Horizons is scheduled for August 26.
We read on the official website magic.wizards.com .
We also need to delay adding the new Historic Brawl to this update. For players looking forward to it, we’re adding the Historic Brawl (Free) event on August 12, which will run until the queue becomes available.
