Grindstone Price

Updated 2026-07-30

Grindstone from the Masterpiece Series Kaladesh Inventions is a prestige treatment of one of Legacy's cornerstone combo cards. The original Tempest printing serves as a key piece of the Painter's Servant combo that wins by milling the opponent in a single activation. The Kaladesh Inventions frame presents the card in the steampunk aesthetic of Kaladesh's artifact world, at a level of production quality that exceeds any standard booster insertion. Masterpiece Series cards were seeded at extremely low rates into Kaladesh draft boosters, producing some of the lowest per-card populations among widely distributed Magic treatments. Price data shows fractional movement over seven and thirty days, effectively flat at current levels. The base card's ongoing Legacy relevance in Painter combo decks provides sustained player demand, while the Inventions treatment captures the collector segment that prioritizes rare art presentations. This copy benefits from both demand vectors simultaneously.
