Professor Onyx urged the twins to prepare for the dark mage Extus, sounding very much like someone familiar with the rise of tyrants.

Where it came from
Professor's Warning was released in 2021 as part of the Strixhaven: School of Mages expansion for Magic: The Gathering. The set is themed around a magical university, with cards categorized by five distinct colleges, each representing a specific two-color mana philosophy. This instant spell captures the academic, high-stakes atmosphere of the setting, serving as a protective tool for creatures caught in the chaotic environment of the school.
The artwork was created by Kieran Yanner, a prolific illustrator known for his dynamic character work within the game. Yanner designed the piece to convey the immediate, urgent sensation of a magical alert, utilizing the visual motifs consistent with the Witherbloom and Quandrix aesthetic influences found throughout the set. Upon its debut, the card was received as a functional utility piece in limited formats, valued for its ability to provide minor protection while fueling graveyard mechanics.
