# Keening Stone Keening Stone represents a niche but meaningful piece of Magic's artifact history. Collectors value it primarily as a functional mill engine that appeals to graveyard-focused players and casual deck builders. The card's appeal lies in its straightforward design: it mills opponents while providing a repeatable effect that scales with gameplay length. The retro frame treatment in The Brothers' War set attracts collectors interested in nostalgic aesthetics and alternative art presentations. The foil variant commands modest premiums among those seeking premium versions. Most collectors view this as a solid utility piece rather than a chase card, making it accessible for those building themed collections around mill strategies or artifact-focused sets without significant investment barriers.
