# How to Keep an Izzet Mage Busy This playtest card from Mystery Booster represents an interesting artifact of Magic's design process. The humorous title and unconventional mechanics showcase R&D's experimental approach during development. Collectors value these cards as windows into how designers iterate on mechanics before finalization. The playtest series holds appeal primarily to players interested in design philosophy rather than competitive utility. Since these cards were never tournament-legal, they occupy a niche in collections focused on Magic's behind-the-scenes history. The nonfoil-only printing keeps availability straightforward, though Mystery Booster's limited print run means finding specific playtest cards requires patience and searching.
