Stoneforge Mystic Price

Updated 2026-09-20

Stoneforge Mystic in Grand Prix Promo treatment is the rarest frame for one of Legacy and Modern's defining white creatures. The Grand Prix Promo distribution model issued these as prizes to high-finishing competitors at sanctioned Grand Prix events, which means the total population is tied directly to tournament attendance over the event window rather than any production print run. Stoneforge Mystic is banned in Modern and a mainstay in Legacy and Cube, sustaining competitive player demand for copies in preferred art and treatment. Price movement over the past 30 days is notably stronger than the 90-day trend, suggesting recent buying pressure has accelerated relative to the prior quarter. Grand Prix Promos for format-defining staples are a distinct collector category with a ceiling determined by how many were awarded and how many remain in ungraded circulation. Graded population data is material to evaluating this card's holding position.
