Reliquary vs Moxfield: a deckbuilder beside a collection that knows its decks

Updated November 9, 2026

Choose Moxfield to build and share decks: it is a deckbuilding website first, with collection tracking beside it. Choose Reliquary to know where every copy you own is and which decks claim it, and to let an assistant work with that. The two work together: build in Moxfield, import its collection CSV and decklists into Reliquary, and write a Moxfield CSV back out when you want it.

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. Moxfield's collection counts what you own, and players have asked on its feedback board for copies tied to decks (below). 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. 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, and trade matching sets your lists against the wantlist and tradelist another player publishes. Neither has a card scanner. What each costs, exports and offers as an API is in the table above.

Moving from Moxfield

Export the collection as a CSV file and choose it on Reliquary's Import page, where it is recognised by its columns. Decks come over as pasted text. The Moxfield export guide has the steps, and Moxfield import says what is read.

What players ask for and report

What players ask for or report on Moxfield's feedback board and on Reddit, read on 9 November 2026:

  • Players have asked for strict assignment: the collection showing which deck a copy is in, so a card no longer counts as free for every deck. The request is marked in progress. Moxfield's feedback board, read 9 November 2026.
  • Collection import only adds cards, so keeping it in step with a scanner app means deleting and importing again, or living with duplicates. An r/magicTCG thread, read 9 November 2026.
  • Players have asked for a bulk edit of the collection, as decks have, to change properties such as the playtest flag on many cards at once. Moxfield's feedback board, read 9 November 2026.
  • Players have asked for a native phone app with a card scanner; today they scan in another app and import a CSV. Moxfield's feedback board, read 9 November 2026.

Questions

Can I keep building decks in Moxfield?

Yes. Paste a deck's text export into Reliquary's Deck tab, open the deck there, and claim your cards: Reliquary takes the copies no other deck claims and lists what is missing.

Why paste a deck instead of linking it?

Reliquary reads a Moxfield link with one plain request and stops if it is refused. A pasted list always works.

Is a Moxfield proxy kept as a proxy?

Yes. A card marked as a proxy in Moxfield's file comes in as a proxy and is named as one wherever it shows.
