What is Digimon EX-13?
Digimon EX-13 CHIVALROUS XIII (シヴァルラス サーティーン) is the 13th Extra Booster for the Digimon Card Game, themed on the Royal Knights. All 13 Royal Knights get new support cards and gold special parallels. A pack holds 6 cards, a box holds 24 packs, and the set has 81 cards.
The secret rares are Imperialdramon: Paladin Mode (インペリアルドラモン：パラディンモード) and Omnimon: Merciful Mode (オメガモン：マーシフルモード). Buying a box also gets you a box bonus pack with parallel cards.
A Japanese Digimon card player’s X post on October 7 said EX-12 is heavily discounted in shops while EX-13 carries a big premium. They asked whether EX-13 will only rise if it sells out in shops, or ease a little once Premium Bandai pre-orders arrive. The official site shows EX-13 is also taking pre-orders on Premium Bandai.
