# Witty Demon Witty Demon represents an interesting footnote in Magic's design history as part of the Mystery Booster Playtest Cards from 2019. These cards were experimental designs never intended for standard play, making them inherently collectible as glimpses into Wizards' internal development process. Collectors view playtest cards as curiosities that reveal how designers iterate on mechanics and flavor. The nonfoil-only status limits variant options, which some collectors prefer for consistency while others find restrictive. The card's rarity designation reflects its experimental nature rather than market scarcity. For many, Mystery Booster playtest cards hold appeal primarily as historical artifacts and conversation pieces rather than competitive staples, attracting collectors interested in Magic's behind-the-scenes design work.
