Namor the Sub-Mariner (Borderless) (0391) Price

Updated 2026-08-23

Namor the Sub-Mariner in Borderless treatment from Marvel Super Heroes is a premium crossover card from Wizards of the Coast's collaboration with Marvel Comics, featuring one of Marvel's most iconic characters in the Borderless frame. Marvel Super Heroes represents a Universes Beyond crossover bringing superhero IP into Magic, and Namor is among the highest-profile characters in the initial release. The card has been commercially available for less than 90 days, so no 90-day price history is available: price discovery on recently released cards is still in progress. The 7-day reading shows positive movement while the 30-day reflects a sharp pullback from the initial launch price, a pattern typical of high-IP cards that spike on release and correct as initial enthusiasm normalizes. The Borderless treatment commands a premium over the standard frame version. Long-term price will depend on the card's competitive applications and sustained collector interest in the Marvel Super Heroes Universes Beyond set.
