Seedborn Muse (Rainbow Foil) Price

Updated 2026-08-04

Seedborn Muse in the Rainbow Foil treatment from the Secret Lair Drop Series is a premium Commander collectible built on one of the format's most powerful effects. The card untaps all permanents at the start of each opponent's untap step, generating massive incremental advantage in a four-player pod by effectively giving the controller multiple extra turns of mana. The Rainbow Foil finish is the primary premium driver, applying a treatment unavailable through regular product channels. The card has seen marginal softness over the trailing week and month, consistent with post-release price normalization rather than a structural deterioration of the underlying bid. Secret Lair singles that serve as Commander staples tend to find a durable floor once initial speculative positioning unwinds, because the underlying card demand is persistent across Commander deckbuilding. Watch for a standard printing of Seedborn Muse appearing in an upcoming Commander precon, as that would be the most significant headwind to this specific version. Current trajectory is modestly negative but the move is small.
