Bandai revealed Battle Spirits Saga: Lore Set 1, a new boxed set, for release into retail on September 29, 2023.

This is a new product type for Battle Spirits Saga that includes a 30-page illustrated Lore Book that has a gold foil cover. The book details the lore of Battle Spirits Saga’s past and alludes to events in future sets. The set comes with 20 brand new cards, featuring a rainbow holo and gold foil design, that strengthen archetypes from BSS01 and BSS02. It also includes two False Gods BSS02 Booster Packs that contain random Gundam collaboration cards.

Bandai announced a new Battle Spirits Saga TCG line, consisting of a booster set, starter, and a core box, for release in April (see "'Battle Spirits TCG' Back to Life").
