Bundles are packs of multiple cards. Bundles typically contain five (5) cards per bundle. It is an efficient way to acquire cards more quickly to build your collection.
Bundles are sold via auction only. The sale price is determined by the market. After a bundle is sold via auction, if the cards are all of the same scarcity, the value of each card will be determined by the overall price of the bundle divided by the number of cards in the bundle.
