| Crimson Invasion Prerelease Kit
The Crimson Invasion Prerelease Kit is a special product given to participants at the start of Prerelease Tournaments for the Crimson Invasion expansion. Prerelease Tournaments for the Crimson Invasion expansion were held on the two weekends prior to the release of the expansion, on October 21–22, and 28-29, 2017. Each Kit contains a random set of predetermined cards designed to enhance the experience of the Limited format tournament that follows.
Included in each Prerelease Kit is a 23-card Evolution pack that includes one of four specially stamped Prerelease cards for the expansion, as well as four booster packs. The Prerelease cards for the Crimson Invasion expansion are Alolan Raichu, Salazzle, Regirock, and Registeel, with each containing a group of Pokémon cards that are focused around a particular type respectively: Grass-type, Psychic-type, Fighting-type, and Metal-type.
The Crimson Invasion Prerelease Kits provided a number of exclusive Non Holofoils of cards which were only released as Holofoils in Crimson Invasion booster packs: Alolan Raichu, Gengar and Bewear. Alolan Raichu would later be made obtainable in the Clanging Thunder Theme Deck.
