Each time the player wins a battle, they are awarded with a construction card part. There are 280 parts in total, consisting of 140 lower parts and 140 upper parts. These are divided into two groups, with each group having 70 lower parts and 70 upper parts. A lower part and an upper part from the same group can be combined to form a construction card, resulting in 4900 possible construction cards in each group, or 9800 construction cards in total.
Before being constructed, the resulting card can be previewed; this preview only features a greyscale version of the card's artwork, the card's name, and the part numbers. After construction, the card's color artwork can be viewed, its stats are available, and the part numbers in its description are followed by a star.
