# Bear with Set's Mechanic This Mystery Booster Playtest card represents Wizards of the Coast's internal design exploration from 2021. Collectors value these cards as windows into how developers test mechanics before official release. The "Bear with Set's Mechanic" concept demonstrates iterative design—pairing a simple creature with whatever mechanic the set emphasizes. Mystery Booster Playtest cards hold appeal for players interested in design history and completionists building full set collections. The rare designation and nonfoil-only printing make it moderately scarce. These cards weren't intended for tournament play, which adds to their collectible mystique. Serious Magic collectors appreciate them as authentic artifacts of the game's development process rather than finished products.
