Terastal Festival ex Booster Box - SV8a: Terastal Fest ex (SV8a)

The Terastal Festival ex subset largely contains reprints of various notable Pokémon and Trainer cards released in 2023 and 2024, including reprints of Pokémon ex and ACE SPEC cards. This set also debuts Eevee and the Eeveelutions as Tera Pokémon ex, and introduces a new Mirror Holofoil Poké Ball pattern that can appear on certain cards. Like in the Pokémon Card 151 subset, the Mirror Holofoil Poké Ball pattern has a chance to be a Master Ball pattern instead.

Terastal Fest ex will be released in Japan on December 6, 2024, and in Taiwan and Hong Kong on December 20, 2024. Each booster pack of Terastal Fest ex contains 10 cards, one of which is guaranteed to be a Pokémon ex. Each booster box contains 10 booster packs. Cards other than Pokémon ex and ACE SPEC cards do not have rarity symbols. Cards within this set are included in the English Prismatic Evolutions special expansion.
