Undying Rage [Foil] appears in the Magic: The Gathering Eternal Masters set as an Unknown rarity print and occupies a low-price niche at approximately $0.06. Collectors seeking foil versions will note its modest market demand and limited impact on competitive formats. The card's value makes it a common acquisition for set-completion or bulk foil lots rather than investment portfolios. Condition and grading can still affect individual sale prices despite the low baseline.
