| Lost Thunder Build & Battle Box
The Lost Thunder Build & Battle Box is a special product given to participants at the start of Prerelease Tournaments for the Lost Thunder expansion. These tournaments were held on the two weekends prior to the release of the expansion: October 20-21, and 27-28, 2018. The boxes were later made available to purchase at retail stores. 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 Lost Thunder expansion are Suicune, Raikou, Giratina, and Tapu Lele, with each containing a group of Pokémon cards that are focused around their respective types: Water-type, Lightning-type, Psychic-type, and Fairy-type.
The Lost Thunder Build & Battle Boxes provided exclusive Non Holofoil versions of cards only available as Holofoil in Lost Thunder booster packs: Ampharos and Naganadel. Both Ampharos and Naganadel would later be made available in the Storm Caller Theme Deck.
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, with no more than 2 copies of a particular Supporter.
