# Chimney Goyf Chimney Goyf represents Mystery Booster's playful approach to design, functioning as a humorous callback to Tarmogoyf, one of Magic's most iconic creatures. Rather than a serious tournament card, it's a novelty piece that appeals to collectors who appreciate the set's experimental nature and inside jokes. Collectors value Mystery Booster Playtest Cards primarily for their uniqueness and limited print run. These cards were never intended for regular distribution, making them inherently scarce. Chimney Goyf's rarity designation and nonfoil-only status further restrict availability. For many collectors, these playtest cards represent a fascinating glimpse into Wizards' design process and serve as conversation pieces rather than competitive staples.
