The Sun & Moon era marked a pivotal moment in Japanese Pokémon TCG collecting. Released in 2017, this set introduced the Alola region's new starter forms and established design conventions that would define the generation. The reverse holo treatment became increasingly popular among collectors during this period, offering an aesthetic alternative to standard holos while maintaining accessibility and visual appeal. Popplio, the Water-type starter, represents the charming appeal of early-generation Alola discoveries. The reverse holo printing catches light beautifully across the card's surface, highlighting the artwork's delicate details. Collectors value Popplio cards for their connection to the generation's nostalgic appeal and the reverse holo's elegant presentation.
