The Pokémon Mega Evolution set represents a significant chapter in the TCG's modern era, capturing the excitement of the beloved Mega Evolution mechanic that defined a generation of the video games. Released in 2025, this set continues the tradition of celebrating transformative Pokémon moments while maintaining the reverse holo aesthetic that appeals to collectors seeking visual variety alongside standard versions. Grumpig, the psychic swine evolution, appears here in reverse holo treatment—a format that inverts the typical shine pattern to create a distinctive look. Collectors appreciate Grumpig for its character design and the artistic interpretation of this beloved Pokémon, making both regular and reverse versions sought-after additions to focused collections.
