deck-sync

Sync deck card lists between local files and Archidekt.

Usage

./ritual deck-sync [decks...] --download-changes
./ritual deck-sync [decks...] --upload-changes

Arguments

Argument	Description	Required
[decks...]	Deck names to sync (matched case-insensitively, no .md). If omitted, syncs all Archidekt-sourced decks.	No

Each name is matched case-insensitively with a unique-substring fallback; an ambiguous name is reported and skipped. See List Resolution.

Options

Option	Description
--download-changes	Pull remote changes from Archidekt into local deck files
--upload-changes	Push local changes to Archidekt

One of --download-changes or --upload-changes is required. They cannot be used together.

How It Works

Prerequisites

You must be signed into Archidekt before syncing:

./ritual login archidekt

Decks must have been imported from Archidekt (i.e., they have sourceUrl and sourceId in their YAML front matter).

Download Changes (--download-changes)

1. Fetches the current deck state from Archidekt
2. Compares cards and quantities against the local deck file, per board (Main, Commander, Sideboard, Maybeboard) and by card name
3. Applies any differences to the local file, respecting each card’s board:
   • New cards are added to the section matching their remote board (e.g. a card in the Archidekt maybeboard is added to the local ## Maybeboard section, creating that section if it does not exist). A newly created section is inserted in canonical board order (Commander, Main, Sideboard, Maybeboard) without reordering your existing sections
   • Removed cards are deleted from the board they were removed from
   • Quantity changes are applied in-place within the matching board
   • A card that moved between boards on Archidekt is removed from its old board and added to the new one
4. Records all changes in the deck’s .changes.md changelog. Card names are written quoted, and changes that target a non-main board are annotated with the destination, e.g. Added "Cavern-Hoard Dragon" to Maybeboard or Removed "Lightning Bolt" from Sideboard
5. Sets lastSynced timestamp in front matter

Upload Changes (--upload-changes)

1. Verifies you own the Archidekt deck (skips non-owned decks with a warning)
2. Fetches the current Archidekt deck state
3. Compares local cards and quantities against the remote state (by card name only, across all boards — see note below)
4. Pushes differences to Archidekt via their batch API:
   • New cards are resolved by name and added
   • Removed cards are set to quantity 0
   • Quantity changes are set to the new absolute value
5. Sets lastSynced timestamp in front matter

What Is Compared

Sync compares card names and quantities. Downloads additionally respect the board a card lives in (Main, Commander, Sideboard, Maybeboard), so cards land in the right section locally.

The following are intentionally ignored at this time:

• Specific printings (set code, collector number)
• Card finish (foil, etched)
• Labels and categories (beyond mapping to a board)
• Card condition

Note on uploads: uploads ignore board placement. The Archidekt batch API path used here cannot yet target a specific remote board/category, so moving a card between boards locally is not pushed (it would otherwise re-add the card to the default mainboard on Archidekt). Board-aware behavior currently applies to --download-changes only.

Front Matter

After a successful sync, a lastSynced field is added or updated in the deck’s YAML front matter:

---
name: 'My Deck'
sourceId: '12345'
sourceUrl: 'https://archidekt.com/decks/12345'
lastSynced: '2026-04-02T12:00:00.000Z'
---

Examples

Download changes for a specific deck:

./ritual deck-sync black-panther --download-changes

Upload changes for multiple decks:

./ritual deck-sync black-panther oops-all-soldiers --upload-changes

Sync all Archidekt decks (download):

./ritual deck-sync --download-changes
