Swan Song (1591) (Rainbow Foil) Price

Updated 2026-08-10

Swan Song in the 1591 Rainbow Foil treatment from the Secret Lair Drop Series commands a premium over standard versions by pairing a Legacy and Commander staple counterspell with one of the highest-specification foil finishes Wizards of the Coast produces. Swan Song is a one-mana blue instant that counters noncreature spells and sees genuine play in Legacy blue strategies and Commander, meaning this copy has both competitive and casual demand behind it. Rainbow Foil treatments are produced in limited quantities tied to Secret Lair release windows and cannot be reprinted in the same finish, creating a ceiling on available supply. Price has trended upward over both the seven and thirty day windows. The consistent upward direction suggests collector appetite for premium-finish staples is broad enough to absorb available supply at current levels. Cards in this tier with genuine competitive play tend to have stickier demand than pure collector pieces.
