# Yawgmoth's Testament Yawgmoth's Testament represents an interesting footnote in Magic's design history as part of the 2019 Mystery Booster playtest cards. These cards were experimental designs never intended for standard release, making them curiosities rather than competitive staples. Collectors view playtest cards as windows into Wizards' design process, valued more for their historical significance than gameplay impact. The nonfoil-only printing limits availability slightly. Most collectors appreciate these cards for their unique frame treatment and the insight they provide into what might have been. Testament appeals primarily to players interested in design philosophy and completionists building Mystery Booster sets rather than those seeking powerful tournament cards.
