Reliquary vs Deckbox: an inventory site beside a collection that knows its decks

Updated November 9, 2026

Choose Deckbox for a long-running website that keeps your inventory, your decks and your trades in one place. Choose Reliquary to know where every copy you own is and which decks claim it, and to let an assistant work with that. Moving is a CSV file each way: Reliquary reads Deckbox's inventory export and writes a Deckbox CSV back out.

Each fact is from the sources below, read on the day given. A dash: no source says.

Where they differ

The difference is allocation. In Reliquary every copy you own is in exactly one place: a binder, a box or a deck. A deck claims copies from what you own, and two decks never count the same copy without saying so: a shared copy is named with every deck that claims it and where it really is. On Deckbox, deck tools that track a deck's exact printings in your inventory are a Premium feature. Card allocation across decks has Reliquary's rules.

In Reliquary a proxy is named as one wherever it shows, and left out of a value unless you ask. Both sites trade: Reliquary's trade matching sets your lists against the wantlist and tradelist another player publishes, and names proxies on both sides. Reliquary also has an MCP server and a REST API, so an assistant such as Claude or ChatGPT reads and changes your collection under the same rules.

The free plans differ too: the table above has what each holds, what each costs, and where each runs.

Moving from Deckbox

Export the inventory as a CSV file on Deckbox's desktop site, with the Scryfall ID column if it is offered, and choose it on Reliquary's Import page, where it is recognised by its columns. Decks come over as pasted text. The Deckbox export guide has the steps.

What players ask for and report

What players ask for or report on Deckbox's forum, read on 9 November 2026:

  • Players have asked for a public API to read or update a collection from a script or a scanner; in 2024 an admin said it had not yet reached the top of the list. Deckbox's forum, read 9 November 2026.
  • Players have asked to change condition, edition or tags on many cards at once, so an import with the wrong defaults need not be fixed card by card. Deckbox's forum, read 9 November 2026. Partly answered: in October 2026 Deckbox added batch changes of condition and language for Premium, per its Premium page; editions are still changed one by one.
  • New printings, such as Secret Lair cards, promos and double-sided tokens, are often missing until a player reports them in a long forum thread, and some rarities are wrong. Deckbox's forum, read 9 November 2026.
  • Private decks, free for accounts made before 2014 until late 2025, now need Premium; staff say they were always Premium and newly enforced. Deckbox's forum, read 9 November 2026.

Questions

Will my exact printings come across?

Yes, when the export carries Deckbox's Scryfall ID column: each row then names its exact printing. Without it, a printing is found by the card's name, set and number.

Can I go back to Deckbox later?

Yes. Reliquary exports your collection as a CSV file in Deckbox's layout.

Where does Reliquary's card data come from?

From Scryfall. The catalogue is loaded from Scryfall's card data, and a set that gains new cards is pulled in nightly.
