Raging Surf, released in 2023, arrived during a period of sustained enthusiasm for Japanese Pokémon TCG releases. The set continued the tradition of premium double rare cards—special full-art treatments that showcase alternative artwork alongside competitive gameplay options. Japanese releases of this era maintained strong collector interest through carefully curated card pools and artistic presentation. Tapu Koko ex represents the legendary guardian deity of Alola in its ex form, rendered in full-art style. The electric-type deity holds particular appeal for collectors drawn to mythological Pokémon and striking visual compositions. As a double rare variant, this card captures the character's dynamic energy while maintaining the playability that defines ex-era releases.
