This is a story about desire. It is desire for power, desire for companionship, desire for approval, desire for discovery, and everyone is racing to get what they want first. For centuries, the untamed jungles of Ixalan have hidden a coveted secret: Orazca, the city of gold, which houses a mysterious artifact, the Immortal Sun. But no secret can remain undiscovered, and no treasure can be taken uncontested. The dinosaur riding warriors of the Sun Empire and the merfolkshamans of the rival River Heralds are met by the vampire conquistadores of the Legion of Dusk and the pirates of the Brazen Coalition.
Vraska poses as a pirate on the high seas, while Jace Beleren is stranded on the plane with loss of all his memories.
As part of the preview season, Wizards of the Coast distributed trackable game pieces to stores, fans, volunteers, and some well-known community folk. As game pieces travelled from from geochache to geocache, the distances they travelled influenced the release of preview cards.
Prerelease Events took place on September 23, 2017.
Dino-Sized Weekend: The weekend of October 28–29, stores around the world host six-pack Sealed events, three-pack Draft events, and very special dino-sized Draft events using four packs of Ixalan instead of three.
Mid-Season League: Running November 6 through December 3, stores can run Ixalan Mid-Season Leagues.
As a first, there is also a "Dino sized" 9-card Buy-a-Box booster. This contains an extra Buy-a-Box promo card and the equivalent contents of two Standard Showdown prize boosters. The booster contents will only be available in English and Japanese.
