Astroblazer (占征；sensei) is a family introduced in BS56. It exists in Spirit cards of all colors, and is one of the main families in the True Rebirth Saga. The name is a pun from the term 占星 (astrology), with the word 征 (subjugate) replacing 星. Cards in this family always have the Rare rarity or higher, with the Proximate family being more common among all the cards, stressing out the higher position of these Spirits in the lore.
Instead of having a deck to themselves, the Astroblazers are spread across the new decks in the set.
