|Obsidian Flames Build & Battle Box
The Obsidian Flames Build & Battle Box was released as a prelude to the Obsidian Flames expansion and offered people the opportunity to experience the cards before their general release on August 11, 2023. Tournaments were typically held on the weekends of July 29-30 and August 5-6, 2023. Boxes could also be purchased from stores in the Prerelease Program from July 28, 2023; they were also included in copies of the Obsidian Flames Build & Battle Stadium, which were sold from August 25, 2023.
Each box included a ready-to-play 40-card deck plus four Obsidian Flames booster packs to potentially integrate useful cards into it. Decks comprised two of four possible groups of cards, including an alternate-art promotional card, as well as 17 basic Energy cards and an assortment of Trainer cards. The possible promotional cards included Palafin, Cleffa, Togekiss, and Mawile. Obsidian Flames Build & Battle Boxes were categorized as Play Level 2.
The boxes could provide exclusive Non Holofoil versions of cards only available as Holofoil in Obsidian Flames booster packs: Palafin, Toxtricity and Togekiss, as well as both Professor Sada's version of Professor's Research and Professor Turo's version of Professor's Research from Scarlet & Violet.
