# Imaginary Friends Imaginary Friends represents a fascinating artifact from Magic's design process. As part of the 2019 Mystery Booster Playtest Cards, this card offers collectors a glimpse into how Wizards of the Coast experiments with mechanics before official release. The playtest set itself has become increasingly sought after by those interested in game design history and developmental artifacts. Collectors typically view these cards as curiosities rather than tournament staples. The nonfoil-only printing limits variant options, making condition and centering particularly relevant to enthusiasts. These cards occupy a unique niche—they're neither standard legal nor truly vintage, but they document the creative process behind Magic itself. For many collectors, that historical documentation is the primary appeal.
