Temporal Forces arrived in 2024 as a flagship expansion celebrating Pokémon's time-travel narrative themes. The set introduced fresh mechanics and nostalgic callbacks that resonated with both competitive players and collectors navigating the modern era of the TCG. Cosmos Holos brought visual innovation to standard releases, while Pokémon League Stamp promos marked official tournament participation—making these cards historically significant markers of the contemporary competitive scene. Metang, the steel-psychic evolution line representative, appears here with the distinctive Cosmos Holo treatment that creates dimensional depth across the card's surface. This promo version commemorates League participation and stands apart from standard printings. Collectors seek League Stamp promos for their official competitive heritage and the aesthetic enhancement the Cosmos Holo finish provides to Metang's metallic design.
