Import what you already have
A ManaBox CSV export goes straight in. Rows are matched against a local Scryfall mirror, and anything that will not resolve waits in a review queue instead of entering the collection as a guess.

MTG collection tracker for collectors
Magic: The Gathering collectors, traders and storefront-style sellersImport a collection you have already catalogued, keep every printing, finish and condition distinct, and know which binder page a given copy is sitting on. Decks, trades and marketplace listings all read from that same inventory.

A ManaBox CSV export goes straight in. Rows are matched against a local Scryfall mirror, and anything that will not resolve waits in a review queue instead of entering the collection as a guess.
Finish, condition and language live on the holding, and each copy is placed in a real container — a binder page and slot, or a labelled box. The question it answers is which shelf the card is on, not just whether you own one.
Nightly Scryfall pricing for each individual printing, plus a daily snapshot of what the whole collection is worth, charted so you can see which way it is moving.
One grammar across everything you own — t:creature c>=WU set:mh3 tradebinder:true — with OR, parentheses, quoted phrases and exclusions.
A deck builder that shows prices and what you already own on every card, a trade binder with friend codes and trade requests, per-item public, unlisted or private sharing, and a Magic catalog anyone can browse without an account.
Pro accounts connect their own CardTrader and ManaPool seller accounts, push sale-marked inventory as live listings, and confirm each sale before anything leaves the shelf.
