Champion (成熟期; Seijukuki) is a family in the trading card game that premiered in CB02.
The name comes from the term of the same name used in the Digimon Franchise, and refers to one of the evolution stages of Digimons. It is one stage after Rookie and one stage before Ultimate. It is usually the "second stage" of the partner Digimons in anime as most of them started out as Rookie.
In game, a lot of the Spirits in this family possess the keyword: Super Digivolution, representing the evolution relationship between the Champion stage and Ultimate stage. The cards in the family are also the target of Digivolution, showcasing how it is an evolved form of Rookie.
