Omens of Chaos brought the world of Strixhaven into Magic: The Gathering through its connection to Seanan McGuire’s Strixhaven: Omens of Chaos. The collection focused on the first-year students and the pressures of magical academia, with artwork by Nathaniel Himawan, Bryan Sola, Arif Wijaya, and Andrew Mar depicting the dangers and ambitions of life at the university. Its direct tie to the bestselling novel made it a distinctive collectible for fans of both Magic and the Strixhaven story.
