ST-25 Rubeusdramon starter deck

ST-25 is the physical starter deck built around Rubeusdramon. The English and Japanese product pages both date it 5 December 2026. The Japanese page lists ¥1,980 including tax. The English page does not list a price. The 17 card names are not published.

What the box contains

The publisher’s contents line is 54 cards across 17 types, with the rarity split 5 common, 4 uncommon, 4 rare, 3 super rare and 1 promo. Also in the box: 2 playsheets, 4 index cards, 1 Digimon Alysion serial code, and booster packs from BT-27. The English product page explicitly specifies one BT-27 pack for the English version; the Japanese product contains two. The promo card name is not published. Rubeusdramon is the face Digimon: on the in-app line it is the mega of Tokomon, Gemmon, Liskmon and Reptilimon, which is a separate fact from the boxed list.

People looking for upgrades will not find a published upgrade path. The product pages do not recommend swaps, and the mobile card pool is not finished. When names appear, they belong in the table on the card list as well as here. Until then the honest contents are the counts above, the price in yen, and the two dates.

Rubeusdramon’s own public profile, from Wikimon, calls it a Mega Dragon Warrior Vaccine. That profile is not the deck list. ST-26 Yukinamon is the paired physical deck at the same price and the same official date, with its own empty 17-name list. The starter-deck index compares both physical products and the in-app starters.

Questions

Is the full card list available?

No. Seventeen numbers are reserved. Names, colors and rarities of those cards are blank in public tables.

What does the serial code redeem?

The product page says a code is included. It does not say what it grants, where it works, or when it expires.
