as promotions) with other players through the "Classifieds," which acts as a searchable bulletin board on which players post buy requests for certain cards, or notices of cards they own that are available for trade/sale. In previous versions of Magic Online, other suggested methods of trading existed, but have since been abandoned in favor of the Classifieds, as the other methods were inefficient and prone to spam. A large number of the users posting offers to buy or sell are entrepreneurs with large collections looking to make a profit by selling cards at their own websites in addition to their in-game trades.

Since the maximum number of copies of a card in a deck is usually 4 (the major exceptions being basic lands), any duplicates of a card beyond the fourth are unnecessary for deck building and can be traded off. Due to the ease of trading away unwanted or extra cards, transaction costs on Magic Online are very low. While in real-life, the money gained by finding a better price at a different
