The Pokémon TCG's Battle Region set (s9a) is a Japanese language expansion focused on Pokémon from the Sinnoh region, particularly those featured in Pokémon Legends: Arceus.
It introduces "Radiant Pokémon" (a new type of Shiny card, limited to one per deck) and continues the trend of VSTAR cards. The set also features "Sparkling Pokémon," which are Shiny Pokémon with a specific holofoil pattern and rarity, and Character Rare Full Art cards featuring Pokémon Trainers.
