Underworld Breach (2040) (Rainbow Foil) Price

Updated 2026-08-25

Underworld Breach in the 2040 Rainbow Foil Secret Lair treatment combines one of the most powerful recursive combo enablers across Modern and Legacy with a visually distinctive foil treatment that commands its own collector premium. Pricing has been mixed across tracked windows, declining approximately 0.5 percent over seven days while gaining 1.8 percent over thirty days and 13.2 percent over ninety days, a pattern that reflects speculative volatility layered on top of genuine format demand. The card itself remains a key component in combo shells across multiple competitive formats, providing a durable functional floor beneath the premium treatment. Supply of this specific Rainbow Foil printing is limited by the exclusivity of the Secret Lair release format. Near-term direction is uncertain given the mixed short-term signal, but the substantial ninety-day gain suggests underlying demand has been absorbing available supply at an above-market pace.
