| Evolutions Prerelease Kit
The Evolutions Prerelease Kit is a special product given to participants at the start of Prerelease Tournaments for the Evolutions expansion. Prerelease Tournaments for the Evolutions expansion were held on the two weekends prior to the release of the expansion, on October 22-23, 2016 and October 29-30, 2016. 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 the four specially stamped Prerelease cards for the expansion, as well as four booster packs. The Prerelease cards for the Evolutions expansion were Charizard, Gyarados, Mewtwo, and Machamp, with the four different groups of possible Pokémon cards being based on their four types: Fire-type, Water-type, Psychic-type, and Fighting-type.
The Evolutions Prerelease Kits also provided a number of exclusive Non Holofoils of cards only released as Holofoils in the Evolutions booster packs: Ninetales, Poliwrath, Nidoking, Mew, and Hitmonchan. Nidoking and Hitmonchan would later be obtainable in the Mewtwo Mayhem Theme Deck.
Evolution Prerelease Kit structure
Each Prerelease Kit included two of the following four different groups of Pokémon cards, with one group always coinciding with the included Prerelease promo.
Each Prerelease Kit also included an additional random group of predetermined Trainer cards. No matter which group was included, at least one Tierno was provided. Only 3 in any combination of the Supporter cards and 2 in any combination of Item cards were included.
