GX Battle Boost is a Japanese Pokémon TCG High Class Pack expansion from the Sun & Moon era. Released in Japan in 2017 with the set code SM4+, the expansion brings together a broad selection of Pokémon and cards from the early Sun & Moon period. Pokémon-GX play an important role throughout the collection, while the High Class Pack format gives the set a different identity from the standard Japanese expansions released during the same era.
The GX Battle Boost card list features Pokémon such as Solgaleo-GX, Lunala-GX, Tapu Lele-GX, Sylveon-GX, Darkrai-GX, Ho-Oh-GX and many other Pokémon from Alola and previous generations. Regular Pokémon and Trainer cards appear alongside these Pokémon-GX, creating a varied checklist that revisits several cards and mechanics introduced across earlier Sun & Moon releases.
One of the most recognizable characteristics of GX Battle Boost is its selection of special full-art cards. Several Pokémon appear in detailed illustrations that place greater emphasis on their surroundings and interactions, while selected Trainers also receive collectible versions. These cards give the expansion additional visual variety beyond the standard Pokémon and Pokémon-GX included throughout the main collection.
Collectors can find multiple rarity levels and card treatments throughout the Japanese GX Battle Boost card list. Alongside regular Pokémon and Pokémon-GX, the expansion contains Secret Rare cards, Full Art Pokémon and collectible Trainer cards. These additional versions extend the checklist beyond the regular numbering and make the higher-rarity portion an important part of collecting the complete expansion.
All GX Battle Boost cards on this collection page belong to the original Japanese SM4+ expansion and feature Japanese-language card text. As a High Class Pack set, GX Battle Boost brings together cards from different parts of the early Sun & Moon era while adding exclusive collectible versions. This gives the expansion a broad representation of the Pokémon-GX period in a single Japanese set.
