The Signature Spellbook series was a limited run of Magic: The Gathering products released between 2018 and 2020, each themed around a specific planeswalker and their signature spells. Every box included eight curated cards with new art and special frames, plus one random card in foil. The series began with Signature Spellbook: Jace, followed by Gideon and Chandra, featuring iconic spells like Brainstorm, Path to Exile, and Past in Flames. Designed as collectible, flavorful tributes to beloved characters, the Spellbook series was later succeeded by the similarly styled Commander Collection.
