Treat an imported URL as a starting point

A shared deck URL can save typing, but it is not a guarantee that two services describe every card in the same way. Import formats may identify a card by an external ID, a set number, or a title that has more than one printing. DM Value attempts to match that information to its Japanese card catalog and then builds a readable proxy list.

The useful habit is to separate transfer from verification. First import the list. Then review the result as though another person prepared it for you. This makes mismatched printings, omitted external cards, and unexpected quantities easier to notice before they affect a practice game.

Run the five-minute main-deck check

Start with total count, duplicate counts, and the civilization mix. Next scan the cost curve and card types. A sudden cluster at an unexpected cost often reveals a bad match faster than reading every title. Finally, open unfamiliar entries and compare their Japanese name, set information, and rules text with the list you intended to use.

• The main deck contains the intended number of cards for the selected format.
• Copies of key cards match the source list and the format you are testing.
• Civilizations, costs, and card types look plausible as a group.
• Cards with multiple faces or special identities display the expected face data.
• Any catalog warning is resolved or recorded in your test notes.

Review external cards separately

Cards outside the main deck can have different placement and return behavior. Keep the hyperspatial, GR, and other external groups separate while reviewing them. A correct total in the main deck does not prove that these groups were imported correctly.

If an external card is missing, add or correct it before starting the table. During a test, use the destination and routing controls deliberately; DM Value avoids guessing a card-specific destination when the available data is not authoritative enough.

Save a known-good baseline

After the list passes review, give the saved deck a name that identifies the version you are testing. A date, format label, or short change note is more useful than repeatedly overwriting a generic name. When you change several slots, keep the previous version until the new plan has completed at least one practice session.

This baseline makes test results comparable. If an opening-hand problem appears after a change, you can distinguish a deck-building decision from an import mistake and return to the last checked list without rebuilding it from memory.

When a card match looks wrong

Do not compensate by choosing a merely similar card. Record the source URL, the expected Japanese card name or identifier, the displayed match, and the approximate time of the import. That information is much more actionable than a screenshot alone.

You can continue a private test with a clearly labeled substitute if both sides understand the limitation, but the saved deck should remain marked as needing review.
