Deck transfer for Yu-Gi-Oh! Master Duel and Neuron

Import and export Yu-Gi-Oh! decks from Master Duel and Neuron in YDK format and YDKE URLs via Konami's official card database. Directly import decks from YGOPRODECK and other communities.

Konami's official products have never interoperated with community resources, but now with this browser extension, you can bring your decks in commonly-used deck formats directly into the official Yu-Gi-Oh! Master Duel video game and Neuron duel assistant phone app. You can also download any deck from the official card database, including your Master Duel and Neuron decks, and share directly to YGOPRODECK.

Note: the Opera add-ons listing is deprecated due to slow moderation of extension updates. Opera users should install from the Chrome Web Store instead like other Chromium browsers to receive the latest features and fixes.

Linking Master Duel to the official database

Link your Master Duel account to a Konami ID via the data transfer feature. This is found in the hamburger menu as "Data Transfer", or "Data Transfer" in the title screen.

Follow the instructions to create or log in with your Konami ID. Your Konami ID must be associated with a Card Game ID.

After data transfer is set up, the card database button in the top-right of the deck screen should show the decks from your official database account. Furthermore, you should see the export button become available when you view your decks. Make sure you can log into Konami's official card database and access "My Deck" on the website.

If your Konami ID does not have a Card Game ID, you can try logging into your Konami ID in Neuron.

Installing on Safari

Compatible with both macOS and iOS, if Userscripts is supported!

2. Enable Userscripts (iOS) following its instructions.

Installing on Android

Firefox for Android supports browser extensions. Simply install from Firefox add-ons like on desktop.

~~Firefox Beta supports installing extensions beyond the recommended list. If you are interested, you can follow the same instructions as Indie Wiki Buddy to set up. You can either create your own collection or use collection owner 17816848 and collection name deck-transfer-for-master-duel.~~

Unfortunately, most other Android browsers do not support extensions. Kiwi Browser supports Chrome extensions, but I have not tested or used this browser.
