Thwart Price

Updated 2026-07-31

Thwart from Mercadian Masques is a four-mana hard counterspell with an alternative cost that lets a player return three Islands to hand instead of paying its mana cost. That pitch mechanic made it a notable inclusion in blue-heavy Legacy and Vintage decks during its era, and it remains a casual Commander curio for players building permission-heavy blue control shells. At $91.23 NM, the card sits at a price point driven almost entirely by scarcity, as Mercadian Masques had below-average print runs relative to other late-1990s sets and NM copies have steadily left the market. Price movement is flat over both the 7-day and 30-day windows. The market for this card is thin, meaning any sustained player demand or a relevant reprint announcement would move the price sharply. Sellers are in no hurry, and buyers face limited NM supply at the current level.
