Cosmic Eclipse arrived in late 2019 as one of the final mainstream Sun & Moon era sets before the Sword & Shield transition. The set is remembered for delivering bold, experimental artwork across its lineup and introducing several sought-after Pokémon in competitive and collector-favorite forms. It captured a moment when the TCG was experiencing renewed attention and the reverse holo treatment remained a standard premium offering that collectors actively pursued. Blacephalon, the Ultra Necrozma counterpart from Generation Seven, appears here with characteristically vibrant and dynamic artwork that defined Cosmic Eclipse's aesthetic. The Reverse Holo version transforms the card's visual impact through its textured finish, making it particularly striking to collectors who appreciate the interplay between the card's design and the prismatic treatment that reverse holos provide.
