Moxfield vs Archidekt: two Magic deckbuilders and their collections

Updated November 9, 2026

Moxfield and Archidekt do the same job: each is a deckbuilding website first, with a collection kept beside the decks. Which suits you comes down to how you like to build; on the collection side, players ask both for much the same things.

At a glance

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

Where they differ

Players of both report scanning their cards in a separate phone app and import its CSV, as the threads below show. Where each runs, what each costs, how each exports and what each offers as an API are in the table above, each with its source.

On the collection, players report the same gap on both: a card you own counts as available to every deck that lists it, so the collection does not say which deck a copy is in. On Moxfield it is a request on the feedback board, marked in progress; on Archidekt the workaround offered is tagging cards by hand. Both also take a newer scanner export only by deleting the collection and importing it again.

Moving between them

Export the collection as a CSV file and a deck as text from either one. The Moxfield export guide and the Archidekt export guide have the steps. Reliquary, which publishes this page, reads both files; whether each site reads the other's is for their own help pages to say.

What players ask for and report

What players ask for or report on each site's own board or forum and on Reddit, read on 9 November 2026.

Moxfield

Players have asked for strict assignment: the collection showing which deck a copy is in. 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. Moxfield's feedback board, read 9 November 2026.
Players have asked for a native phone app with a card scanner. Moxfield's feedback board, read 9 November 2026.

Archidekt

A card you own shows as owned in every deck that lists it, so a new deck can look complete when it is not. An r/EDH thread, read 9 November 2026.
A collection cannot be updated from a newer scanner export; the team has said a view of the differences would be too heavy for large files. Archidekt's forum, read 9 November 2026.
The deck builder slows on very large lists; staff say it is built for decks of a few hundred cards and point bigger lists to the collection manager. Archidekt's forum, read 9 November 2026.

Questions

Which one tracks a collection better?

Their players report the same limits on both: a copy counts for every deck, and a newer scanner export means importing again. Pick by the deckbuilder you prefer.
