Chivalrous XIII is an Extra Booster, which in the Digimon Card Game means a set that stands outside the main numbered line and is built around a single theme rather than around a story arc. The theme here is the Royal Knights, and the publisher says so plainly: the set is built so that decks for the thirteen Royal Knights get strengthened at once.
What makes this set unusually easy to write about honestly is that Bandai publishes the whole of its structure on the product page. The number of card types, how they split across the rarity ladder, which two cards are the Secret Rares and the names of all thirteen Royal Knights are all stated by the publisher, which means this page can be complete rather than representative.
Quick answer
Chivalrous XIII holds 81 card types, and its Secret Rares are Imperialdramon: Paladin Mode and Omnimon: Merciful Mode. The set’s signature feature is not a card type but a finish: every one of the thirteen Royal Knights has an alternate art with a gold treatment. The Digimon Card Game index covers the game at the level of colour and card type; this page goes a level finer, down to the individual names.
The set, as the publisher states it
These are the publisher’s own figures for the set. They are quoted rather than measured, which matters, because a card count is the kind of number that is easy to estimate wrongly from a card list.
| Field | As published by Bandai |
|---|---|
| Product name | Chivalrous XIII |
| Product code | EX-13 |
| Set type | Extra Booster |
| Release date | 2 October 2026 |
| Card types in the set | 81 |
| Cards in a pack | 12 |
| Packs in a box | 24 |
The rarity split, as published
The rarity ladder in this game runs from Common to Special Card, and the publisher states how many card types sit at each step. Two things follow from reading it as a distribution rather than as a list of names: the set is bottom-heavy by design, and the top of the ladder is deliberately small.
| Rarity | Card types |
|---|---|
| Common | 22 |
| Uncommon | 20 |
| Rare | 18 |
| Super Rare | 12 |
| Ultimate Rare | 3 |
| Secret Rare | 2 |
| Special Card | 4 |
Four card types at the top two steps together is a small ceiling, and it is worth noticing that this is normal rather than stingy: the count describes how many different cards exist at that rarity, not how often one appears. The relationship between a card’s number and its rarity is a separate subject, and card numbers and rarity codes covers it. The publisher notes alongside this table that alternate art and alternate design versions of the listed types exist on top of the counts above.
The thirteen Royal Knights
The thirteen are named by the publisher in the same breath as the announcement that each of them has a gold alternate art. They are listed below in the order the publisher lists them, which is the order of the announcement rather than a ranking of any kind.
| # | Royal Knight |
|---|---|
| 1 | Omnimon |
| 2 | Alphamon |
| 3 | UlforceVeedramon |
| 4 | Magnamon |
| 5 | LordKnightmon |
| 6 | Gallantmon |
| 7 | Dynasmon |
| 8 | Craniamon |
| 9 | Kentaurosmon |
| 10 | Leopardmon |
| 11 | Examon |
| 12 | Gankoomon |
| 13 | Jesmon |
The list is a closed set, and that is the design of the set as much as the design of the group: an Extra Booster built around thirteen named Digimon can buff all thirteen at once, which a normal booster spread across a story arc cannot. The distinction between a Royal Knight and any other Digimon is a matter of the publisher’s reference material rather than of the card game, and the game itself treats them as ordinary cards with ordinary numbers.
The two Secret Rares
The publisher names both cards at the top of the ladder rather than leaving them to be discovered, which is a habit worth knowing about: in this game the identity of a set’s Secret Rares is product information rather than a spoiler.
| Card | What it is |
|---|---|
| Imperialdramon: Paladin Mode | One of the two Secret Rares of Chivalrous XIII |
| Omnimon: Merciful Mode | The other Secret Rare of the set |
What a box adds
Two of the publisher’s stated points are about the box rather than about the set, and they are the part most often missed by people reading a card list instead of a product page.
- An alternate art with every box. The publisher states that each box carries an alternate art card, which is a floor rather than a hope: it is a stated part of the box, not a pull.
- The gold treatment is the set’s feature. The alternate arts for the thirteen Royal Knights are described as carrying a special finish that glows gold, which makes the finish the thing to look for rather than the rarity step.
- The pack and box sizes are unchanged. Twelve cards in a pack, twenty-four packs in a box, as with the rest of the line, so nothing about opening this set differs from opening any other.
What this page does not claim
No prices, and no pull rates. The publisher states how many card types sit at each rarity and gives the pack and box contents, and this page reproduces those statements and stops. It does not estimate how often a given card appears, because the publisher does not publish that, and it does not rank the thirteen Royal Knights by anything, because the publisher has ranked them by nothing. Where the publisher’s product page does not define something, this page says nothing about it rather than filling the gap.
Frequently asked questions
How many cards are in the EX-13 set?
Eighty-one card types, as published by Bandai on the product page. The split runs from 22 Common types up to 2 Secret Rare types and 4 Special Card types, and alternate art versions of the listed types exist on top of those counts.
What are the Secret Rares in Chivalrous XIII?
Imperialdramon: Paladin Mode and Omnimon: Merciful Mode. Bandai names both on the product page rather than leaving them to be found, which is normal for this game.
Which Royal Knights are in the set?
All thirteen are named: Omnimon, Alphamon, UlforceVeedramon, Magnamon, LordKnightmon, Gallantmon, Dynasmon, Craniamon, Kentaurosmon, Leopardmon, Examon, Gankoomon and Jesmon. The publisher lists them in that order, which is the order of its announcement and not a ranking.
What is special about the alternate arts in this set?
The alternate arts for the thirteen Royal Knights are described by the publisher as carrying a special finish that glows gold. That finish is the set’s signature feature, and it applies across all thirteen rather than to one chase card.
Does every box contain an alternate art card?
Yes. The publisher states that each box comes with an alternate art card, which makes it a stated part of the box rather than something that depends on the packs inside it.
