The Terastal Fest 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.
