Help FAQs

Frequently asked questions about using Deckonomicon.

Deck Import

› Does importing a deck publish it automatically?

No. Deck import creates an editable deck record in Brewing, but it does not publish a deck version.

Review the imported cards first, then publish a version when the list is ready for match tracking.

Collection Import

› What happens when a collection import has invalid lines?

Collection import can either stop before saving anything or skip invalid lines and save the valid records.

Use Stop and import nothing when you want an all-or-nothing import. Use Skip invalid lines when you want Deckonomicon to report the rejected lines after saving the valid ones.

Collection Export

› Can I export only part of my collection?

Yes. Collection export uses the current search, filters, sort, and grouping in Archiving.

Clear search and filters before exporting if you want a full collection file.

› Which collection export format should I use?

Use CSV when you want a spreadsheet-friendly file or a detailed local record. Use Custom when you want a plain text list controlled by a custom line format.

For Custom, the default ${quantity} ${name} (${set}) ${collector_number} exports quantity, card name, set code, and collector number. Add tokens such as ${l}, ${f}, ${c}, and ${acquired_at} when you need more detail.

Deck Visibility

› What do Public, Shared, and Private deck visibility mean?

Public decks can be shown to everyone, including in public deck search and player profile pages linked from Profile.

Shared decks are visible to anyone with the deck link and to members of your playgroups. Private decks are visible only to you in Brewing.

Brewing Tags

› What is the difference between a dimension, a category, and a tag?

A dimension is a broad way to organize your cards. It contains categories, which group related tags. You attach the individual tags to cards.

For example, in Game plan → Mana → Ramp, Game plan is the dimension, Mana is the category, and Ramp is the tag. You can choose your own names. See Organize cards with tags for more examples.

› Should I use a global tag or a deck tag?

Use a global tag when you want a label to follow a card across your decks. Use a deck tag when the label applies to that card only in one particular deck. Removing a global tag from a card affects its tags across your decks too.

Global means across your own profile. It does not make the tag public; visibility is a separate setting. Learn more about global and deck tags.

› Can a card have more than one tag?

Yes. A card can have several tags within one dimension or across different dimensions. It can also have both global and deck tags.

This lets you describe several roles or decisions without replacing an existing label. A card may appear in more than one tag group, but that does not add copies to your deck. See how to use several labels.

› Why does a card appear as Untagged?

When you group your deck by Tags, Untagged means the card has no tag in the dimension you selected. It may still have tags in other dimensions.

Choose another dimension in the display controls, or use the card’s Change tags action to add a label in the selected dimension. See how to review your deck by tags.

› How do I use the Tag Assistant?

Open Tag Assistant settings from Brewing Tags to choose which categories or individual tags you want it to use. Save your choices, then open a deck and run the Tag Assistant to update tags for its cards.

Saving settings alone does not tag cards. The assistant uses global tags, so its labels follow those cards across your decks. You can also create and apply your own tags as described in the brewing tags guide.

Publishing

› Does publishing a deck make it public?

No. Publishing a deck version does not change deck visibility.

Publishing records the current list as a stable version. Visibility still controls whether the deck is Private, Shared, or Public.

› Why publish a private or shared deck?

Publish a private or shared deck when you want a stable decklist version without exposing it publicly.

Published versions help track deck changes over time and let match records point to the exact list that was played.

Playgroups

› How do playgroups affect match records?

Playgroups define which players can be selected together in Chronicles records.

A match is saved under one playgroup, and only accepted members of that playgroup can be selected for that record.

Duels

› Who can I challenge to a duel?

You can challenge another accepted member of the selected playgroup.

You cannot challenge yourself. Players with pending invitations are not available for duels until they accept and become playgroup members.

Match Tracking

› What matches can I track?

You can track matches played inside a playgroup, either as standalone records or as part of an ongoing duel.

A match can be best of 1, 3, or 5. Each tracked game needs a winner and can include result details such as turn and reason.

› What do I need before tracking a match?

You need an account, a playgroup, at least two selected players, and a published deck for each player.

The selected decks must be visible to match tracking. Private decks from other players are not available in the match deck picker.

› How do I record a match for someone who is not a Deckonomicon user?

Use a placeholder participant. In Record match, open the player menu on a tile and select Create placeholder participant to add a named stand-in.

Placeholder participants belong to the selected playgroup and can be reused in later records. See Record a match with placeholder players and decks.

› Can I record a match when a player has no published deck?

Yes. Create a placeholder deck from the deck picker to record the deck name, colors, and commander without a full decklist.

A placeholder deck satisfies the deck requirement now. Replace it with a published deck version later. See Record a match with placeholder players and decks.

› How do I replace a placeholder deck in saved match history?

Edit an existing match and select Replace placeholder on an eligible real-player tile. Players can replace their own assignments; the playgroup admin can replace any real participant and can choose an all-playgroup scope.

Select the player's latest published public or shared deck version in the same format, review active and soft-deleted impact plus any color warning, and complete the irreversible confirmation. Placeholder-user assignments are skipped until that user placeholder is replaced, and the source deck is deleted automatically only after its last persisted reference is gone.
