Each Trainer Collection Gift Box was enclosed with one of eight possible Supporter cards depicting characters from Pokémon Sword and Shield. Each one features a set symbol and collection number specific to the product. Seven of these cards feature the character’s signature and are sourced from a range of Japanese products released between 2020 and 2021, while the eighth is a Full Art Secret card sourced from a Western product released in 2023.

Gift boxes also included an accessory tin, matching the trainer Card with a sliding lid and a pack of 64 sleeves with designs analogous to the enclosed card, as well as 3 Packs from each Flame Dance, Eevee 9 Colours and Mew 9 Colours.
