Grindstone Price

Updated 2026-09-30

Grindstone from the Judge Promos program is an exclusive promotional version of a Legacy combo staple distributed to certified DCI judges as recognition for tournament service. The card enables the classic Painter's Servant plus Grindstone combo that mills an opponent out in Legacy, and the judge promo version is the most prestigious copy available to competitive players who run the combo. The 90-day figure shows significant appreciation, with the 30-day continuing positive at a more moderate pace, consistent with a card that made a meaningful move and is sustaining the gain. Judge promo supply is permanently fixed, with no additional copies entering circulation after the original distribution to judges. Demand comes from Legacy players upgrading their copies and collectors acquiring premier versions of combo pieces. The combination of fixed supply and active Legacy play makes this a fundamentally supported name.
