A trade changes a collection in two directions: one card leaves and another arrives. This preview calculates the resulting counts from an inventory you enter, including whether you would give away your last copy. It produces a proposed inventory you can review together before opening the game's nearby exchange screen.
Enter the inventory you actually own. The preview supports one offered card and one received card, reflecting the listing's one-for-one exchange. Matching names are case-insensitive; repeated inventory rows are added together. The file describes a proposal, not a completed trade.
