|Sword & Shield Build & Battle Box
The Sword & Shield Build & Battle Box was a special product given to participants at the start of Prerelease Tournaments for the Sword & Shield expansion. These tournaments were held on the two weekends prior to the release of the expansion: January 25-26 and February 1-2, 2020. The boxes were later made available to purchase at retail stores on February 21, 2020. Each box contained a random set of predetermined cards designed to enhance the experience of the Limited format events in which they were initially distributed.
Each Build & Battle Box included a 23-card Evolution pack that featured one of four specially stamped Prerelease cards for the expansion, as well as four Sword & Shield booster packs. The Prerelease cards could be Rillaboom, Frosmoth, Galarian Perrserker, or Cinccino; each card accompanied a group of Pokémon cards that focused on the following types respectively: Grass-type, Water-type, Metal-type, and Darkness-type.
Sword & Shield Build & Battle Boxes provided exclusive Non Holofoil versions of cards only available as Holofoil in Sword & Shield booster packs: Rillaboom, Inteleon, Galarian Obstagoon, Marnie, and Professor's Research. Marnie and Professor's Research would later become available in various other products; Inteleon was subsequently available in the Inteleon V League Battle Deck.
Each box included two of the following four different groups of Pokémon cards, with one group always coinciding with the Prerelease promo.
Each box also included four random Supporter cards from the following, with no more than two copies of a particular card.
