Changes to Decklist Submission - Powered by Scrollrack

Today we’re unveiling Scrollrack, TopDeck.gg’s brand-new, in-house deck-validation engine, and with it a completely rebuilt deck-submission flow. This is a soon-to-be open source tool for all TCG builders to help validate decklists for various games and formats.

What Is Scrollrack?

Scrollrack is our proprietary service that brings all deck checks directly into TopDeck.gg. Instead of pasting links elsewhere, you’ll submit your decks on TopDeck.gg and get instant, precise validation against official format rules and banned/restricted lists.

Why We Built It

• End Moxfield Reliance Until now, MTG players pasted Moxfield URLs and we outsourced validation. Scrollrack brings every check in-house, reducing third-party load and giving us full control over the experience.
• Simplify Organizer Workflows No more external locking decklists or viewing them on another website. Organizers see, review, and approve decks right in the tournament dashboard.
• Prepare for Every TCG A unified engine makes it easy to add new games and formats, so TopDeck.gg can grow with the community.

How It Works

1. MTG Players
   • Import via Moxfield URL, or paste a plain-text deck list.
   • Standard, Modern, Legacy, Commander, Pauper, Vintage, and most other formats via Moxfield import or plain-text lists
2. Yu-Gi-Oh! Players
   • Paste a text list or upload a .ydk file.
   • Edison & Goat formats are currently supported
3. Organizers
   • View all submitted decks directly in the dashboard.
   • Deck checks are easier than ever.

Future plans:

• Deck Data Lives on TopDeck.gg: all your lists and validation history are stored alongside your tournaments.
• Future Features: as we add more games, expect tournament analytics, win-rate tracking, meta reporting, and more.

API Updates

Our tournaments-v2 endpoint will now return a decklist object whenever possible, complete with card list, game, format, and import source (if applicable). We’re rolling out updated API documentation later this week, so stay tuned for full details on how to consume these new fields.
