Bulk team/year/set trading for base-card collectors — without per-card inventory.

Build a Have or Want around team, year, set, approximate count, and photos. The goal is a fast bulk-lot workflow — never per-card inventory.
Keep it bulk-only: team, year, set, approximate count, and a trust-building photo. If a workflow starts asking for card numbers, it is the wrong workflow.
