Blue Card

The blue cards appeared throughout the Tamers season of Digimon. Created by the Monster Maker Shibumi, the blue cards caused the creation of Guilmon, and the bio-emergence of Terriermon and Renamon (Tamers) .They also allow Guilmon, Terriermon and Renamon to digivolve to Ultimate. This card is also used in Digimon World 3 to go between the east sector and the south sector. When you talk to the tricky Guilmon in Digimon World 3 he will give you a false blue card called a 8lue card when you talk to the tricky guilmon again in the basement of the forest inn he will give you a real blue card. This "blue card" as its called seems to have the power of Calumon stored inside of it. In the Tamers season of digimon it randomly appears from an existing card just when they need it most and disappears afterwards. The blue card is usually created from an existing evolution card.
