Brass's Tunnel-Grinder (Extended Art) Price

Updated 2026-05-06

Brass's Tunnel-Grinder (Extended Art) is executing a sustained climb that rewards early specs. The foil rare has gained +35.7% over 30 days and +7.1% in the last week, building on a recovery arc from its $3.53 trough to the current $5.08 ask. This isn't a spike: the card sits only +4.3% above its 19-day peak, indicating steady accumulation rather than panic buying or dump reversals. The 43.9% lift from trough to current price suggests conviction among buyers willing to stack through resistance. Supply mechanics on Lost Caverns extended art rares remain relevant here; foil scarcity typically compounds upside as pack demand normalizes. Watch whether this card can clear $5.25 to $5.50 without profit-taking. A pullback toward $4.50 would signal bag holders exiting. Monitor if Tunnel-Grinder sees constructed or limited format adoption; current price action alone indicates genuine demand, not speculation runoff.
