HSP cards are cards that were made before Bakugan Battle Brawlers. HSP stood for Holo Sector Points, the number of points a player won for capturing specific Gate Cards in addition to their respective Attribute bonus points (when applicable).
Some differences between the HSP cards and current cards are:
- HSP values
- Command Cards etc rather than Gold, Silver and Bronze
- Negative bonuses
- Aesthetic changes
- Foil Cards unnamed
