Quantum Riddler Price

Updated 2026-08-27

Quantum Riddler is a Promo Pack Mythic from Edge of Eternities, distributed through limited sealed promo packs attached to the standard set release. Promo Pack cards are printed in relatively low quantities compared to standard set cards, creating a modest scarcity premium for the promo version over the regular printing. The 30-day price trend is slightly negative and the 90-day view confirms continued softening, suggesting the promo premium is compressing as market pricing settles from the initial release period. Edge of Eternities is a recent set, and secondary market prices for promo versions are still working through their initial adjustment after product distribution. The functional card is available at a lower price point in the standard version, which limits the ceiling for the promo premium. Buyers who want the Promo Pack version should watch whether the spread versus the standard printing stabilizes at a level that justifies the premium before committing.
