Arcane Signet (1919) (Rainbow Foil) Price

Updated 2026-08-05

Arcane Signet is the gold standard of Commander mana rocks, tapping for one mana of any color in your commander's color identity without restriction. The 1919 treatment is a Secret Lair Drop version featuring a distinctive visual style, and the Rainbow Foil finish amplifies the collector appeal above even other Secret Lair printings of the same card. Secret Lair drops are produced through fulfillment runs of fixed duration, capping supply at whatever volume is ordered during the sale window, and making each treatment a distinct and permanent ceiling. Despite the card's multiple printings, the Rainbow Foil variant occupies a position no other printing replicates, and that scarcity drives the premium over all other Secret Lair editions. The past month's steady appreciation is consistent with a collector piece seeing gradual demand accumulation, as Commander players who want the most visually distinct version compete over a fixed inventory of available copies.
