| Team Up Build & Battle Box
The Team Up Build & Battle Box is a special product given to participants at the start of Prerelease Tournaments for the Team Up expansion. These tournaments were held on the two weekends prior to the release of the expansion: January 19-20, and 26-27, 2019. The boxes were later made available to purchase at retail stores on February 15, 2019. Each box contains a random set of predetermined cards designed to enhance the experience of the Limited format events in which they were initially distributed.
Included in each Build & Battle Box 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 Team Up expansion are Charizard, Zapdos, Nidoqueen, and Jirachi, with each containing a group of Pokémon cards that are focused around their respective types: Fire-type, Lightning-type, Psychic-type, and Metal-type.
The Team Up Build & Battle Boxes provided an exclusive Non-Holofoil version of Erika's Hospitality, which was only available as a Holofoil card in Team Up booster packs.
Each Build & Battle Box included two of the following four different groups of Pokémon cards, with one group always coinciding with the included Prerelease promo.
Each Build & Battle Box also included an additional random group of 4 of the following Supporter cards (3 if the Zapdos Group is present), with no more than 2 copies of a particular Supporter.
