Every Tamer has a favorite type. If a move with the Tamer's favorite type is used in CardTamers Search, it gains additional damage.
By default, Tamers can have up to three creatures. This can be expanded with a DeckBuilder Membership through the DeckBuilder Club. DeckBuilder Memberships can be purchased with Gold Seeds, although a basic DeckBuilder Membership is included with every paid Tamer. DeckBuilder Memberships must be purchased in the order listed below.
