Digimon Card Game's busy 2026 release calendar is closing out with BOOSTER Ignition of X, designated BT-27, and it is arriving with one of the year's bigger thematic swings: the Royal Knights getting powered up by the X Antibody.
Trade listings and distributor pages consistently point to a December 4, 2026 pre-release followed by a December 11, 2026 full release, with only a small handful of outlier sources listing December 14 instead.
The set leans hard into story content from Digimon Story: Time Stranger, continues the Dual Cards mechanic introduced earlier in the year, and ships alongside two new Digimon Alysion starter decks.
Here is what is actually confirmed about BT-27 right now, and where the full card list still has real gaps worth being upfront about.
Bandai's official Digimon Card Game English stream confirmed BT-27: Ignition of X for a December 2026 release, with the Royal Knights receiving X Antibody forms as the set's central theme.
Retailer and distributor listings have since converged on December 4 for the pre-release event and December 11 for the full retail release, which lines up with BT-27 landing roughly seven months after BT-25: Dual Revolution's May 2026 debut.
Distributor trade sheets and retailer product pages list BT-27 at 108 total card types: 40 Common, 26 Uncommon, 21 Rare, 12 Super Rare, 3 Ultimate Rare, 2 Secret Rare, and 4 Special cards, plus each pack holding 12 cards across 24-pack booster boxes.
That rarity breakdown comes from trade and retail sources rather than an official card-by-card reveal, so treat the counts as reliable while the actual card list itself remains unannounced heading into release.
The Royal Knights, previously spotlighted in the EX-13: Chivalrous XIII extra booster, are the set's headline beneficiaries, with BT-27 giving several of them upgraded X Antibody forms.
Collectors who picked up Chivalrous XIII specifically to build a Royal Knights deck have a direct reason to chase BT-27, since the new X Antibody support builds directly on that existing 13-deck Royal Knights framework rather than introducing a separate archetype.
King Drasil, the commanding figure from the acclaimed Digimon Story: Time Stranger video game, makes its Card Game debut in BT-27 as the narrative commander of the Royal Knights.
Framing King Drasil as a story-form support card for Royal Knights decks is a notable crossover move, tying a 2026 console release directly into the physical card game's roadmap rather than keeping the two properties separate.
Digimon pre-release events traditionally give local stores and organized play groups early access to a small allotment of packs before the full nationwide restock, letting players and collectors get a first look at new cards roughly a week ahead of general availability.
Since BT-27's pre-release and ST-25/ST-26's full release fall on the same December 4 date, local game stores running pre-release events will likely have all three products available at once, making that date the practical start of the set's competitive and collecting window rather than just a preview event.
BT-27 continues using the Dual Cards mechanic, letting players treat a single card as either a Digimon or an Option depending on how it is played, with X Antibody digivolution layered on top.
It is worth being precise here: Dual Cards first appeared in BT-25: Dual Revolution back in May 2026, not in BT-27, so this set is extending an already-established mechanic rather than launching a brand-new one.
Decks built around Digimon Beatbreak and Digimon Data Squad both receive continued support in BT-27, specifically the Chiropmon deck from Beatbreak and the Gaogamon deck from Data Squad.
Both decks gain new Dual Cards, giving players invested in those two archetypes a reason to pick up BT-27 even if the Royal Knights' X Antibody theme is not their primary focus.
BT-27 also includes support cards for two new starter decks, ST-25 and ST-26, which release in the same December window and are built around the Digimon Alysion mobile app's cast.
Both starters include their own Dual Cards (Rubeusdramon and Yukinamon respectively) and come bundled with a BT-27 booster pack, making the three releases a genuinely linked December lineup rather than three separate, unrelated products. With three products landing the same week, EVORETRO's 9-pocket binder pages make it easier to keep each set's pulls sorted separately.

With a pre-release, a full release, and two new starter decks all landing in the same window, December is shaping up to be Digimon's busiest month of 2026. Fresh BT-27 pulls deserve protection from the moment packs are opened, and EVORETRO's premium card sleeves are an easy way to start.
