Battle Spirits Collaboration Booster SP: Kamen Rider Hero of Justice [BS-CB19] (Japanese)

CB19, entitled Collaboration Booster SP: Kamen Rider Hero of Justice (コラボブースターSP 仮面ライダー 僕らの希望(ヒーローオブジャスティス)). It is the nineteenth collaboration pack and the nineth collaboration booster with the Kamen Rider franchise. CB19 will be released in Japan on September 25th, 2021. Unlike normal collaboration sets, each pack would include 10 cards, and a core sheet, for players to start playing with a minimum of 4 packs, making it a specially designed pack.

Different from past Kamen Rider Collaboration boosters which focused on a few shows per set, being an anniversary booster to celebrate the 50th anniversary of the Kamen Rider series, the set includes multiple shows and a total of 85 different riders, stretching from Showa, Heisei, to Reiwa period. This is also the first collaboration set with no magics or nexuses and only spirits.

It included a total of 85 cards: 45 Commons, 40 Rares. There are also 85 K50th Rares and 40 K50thSP Rares, in which K50th Rare is the parallel version of Common and Rare, while K50thSP Rare is another parallel version of Rare using actual footage as a part of the illustrations. Each pack would have at least one K50th Rare/K50thSP Rare.
