Full Over Rush Rare & PREMIUM BLACK Highlights

Royal Demons & Kyusei Deck Support

Royal Demons receives new cards designed to strengthen the strategy used by Roa Kirishima, including a new Ace Monster and additional support that expands the deck beyond its earlier Rush Duel releases.

The Kyusei card pool also receives substantial expansion, with new monsters and support cards that allow the theme to function as a more complete strategy rather than relying only on previously released cards.

New Goe Goe & Healthy Themes

Headliner of Reigning also expands the set with new Rush Duel-original strategies beyond Royal Demons and Kyusei. The Goe Goe theme introduces Ninja-focused cards and related support designed to work together as a dedicated deck engine, giving players another option for building around coordinated monster and support effects.

The Healthy theme adds a separate strategy centered on Level 7 Pyro monsters and cards designed to support their playstyle. Together, these newer themes broaden the deck-building range of RD/KP26 and give the booster additional value for players looking to explore fresh Rush Duel strategies rather than focusing only on established anime-based decks.
