Bandai has confirmed Digimon Card Game: Extra Booster Chivalrous XIII (EX-13) for an English release on October 2, 2026, priced at $4.99 USD per booster pack, with the Japanese version following one day later on October 3. This Extra Booster is built entirely around the 13 Royal Knights, one of the franchise's most recognizable Digimon groups, giving the set a tighter thematic focus than a standard main booster release.
Each of the 13 Royal Knights gets a luxurious alternate art card with a notably low pull rate, turning this set into a genuine chase-card release for fans of the group rather than a broad, evenly distributed card pool.
This guide covers what's confirmed about Chivalrous XIII, why the Royal Knights theme matters, and which EVORETRO products make sense once you're opening packs.
According to Bandai's official Digimon Card Game product page, corroborated by the official Digimon Card Game English X account and multiple retailer listings including 88 Cardhouse, here's what's locked in:
With only 81 total card types, this Extra Booster is considerably smaller and more focused than a full main booster set, closer in scope to a themed release than a broad new mechanic drop.
The Royal Knights are one of the Digimon franchise's most iconic groups, and Chivalrous XIII is built specifically to spotlight them rather than folding a couple of Royal Knight cards into a broader, unrelated set. That kind of tight thematic focus tends to appeal strongly to collectors who already follow the group closely, since nearly the entire set ties back to a single, well-defined roster rather than spreading across unrelated characters.
Each of the 13 Royal Knights receives its own luxurious alternate art card, and Bandai has confirmed these carry notably low pull rates. That structure means collectors chasing a complete set of Royal Knight alt-arts are looking at a genuinely difficult full run, since low pull rates across 13 separate targets add up quickly compared to chasing a single chase card in a typical set.
Beyond the Royal Knights themselves, Chivalrous XIII introduces Tamer cards tied to characters from other corners of the Digimon franchise, including Nokia Shiramine from Digimon Story: Cyber Sleuth and Rina Shinomiya from the Digimon World series. Pulling supporting cast from multiple games into a single set gives Chivalrous XIII some crossover appeal similar to how Timeless Bonds (BT-26) drew on Digimon Story: Time Stranger earlier in the year, though on a smaller scale given this release's Extra Booster format.
Chivalrous XIII's 81 card types put it in a similar size range to EX-12 Digital World Shambala, and well below BT-26 Timeless Bonds' 108-card main booster set. Extra Boosters like this one are generally built around a tighter theme with a smaller overall card pool, while main boosters carry a larger mix of staple cards intended for wider competitive use. Collectors deciding how much to invest in this release should factor in that smaller scope: a complete Chivalrous XIII collection is a more contained goal than chasing down a full main booster checklist.
With 22 Commons and 20 Uncommons making up half the set, most of what collectors pull from packs will need basic protection before going into long-term storage. EVORETRO's Perfect Fit inner sleeves give the set's Common and Uncommon pool a first line of protection before cards move into a binder or deck box.
Given how low the pull rates are on each Royal Knight's alternate art card, a hit like this deserves better than a standard sleeve the moment it's pulled. EVORETRO's magnetic one-touch card holder gives a chase pull secure, display-ready protection right away.
Between the 81-card checklist and the added Tamer cards from other franchise entries, collectors following this set closely will likely build up a sizeable pile of singles. EVORETRO's magnetic deck box gives a growing Digimon collection a compact, protective home instead of loose cards spread across storage boxes.
To get ready for Chivalrous XIII's October 2 release, start with these:
October 2, 2026 in English, at $4.99 per pack. The Japanese version releases October 3, 2026.
81 total: 22 Common, 20 Uncommon, 18 Rare, 12 Super Rare, 3 Ultimate Rare, 2 Secret Rare, and 4 Special cards.
The 13 Royal Knights, a well-known group within the Digimon franchise that includes Omnimon and Alphamon, each getting a low-pull-rate alternate art card.
Nokia Shiramine from Digimon Story: Cyber Sleuth and Rina Shinomiya from the Digimon World series, among others.
Smaller. Chivalrous XIII's 81 card types are well below BT-26 Timeless Bonds' 108-card checklist, reflecting its more focused Extra Booster format.
Chivalrous XIII gives Digimon Card Game collectors a tightly themed release built entirely around one of the franchise's most iconic groups, with a genuinely difficult full alt-art run for anyone chasing all 13 Royal Knights. Whether you're after a specific Royal Knight's low-pull-rate card or just want the new Tamer characters in card form, having the right protection ready before October 2 keeps your pulls looking as good as the day you opened them.
