About This Tool

A data-first deck design and validation tool for Yu-Gi-Oh! YGOPRO. It models a deck as main, extra, and side sections and validates card counts, archetypes, and legality against format ban lists. Concepts are kept in a normalized data model so decks can be generated, tested, and ported to YGOPRO with minimal friction. The tool is valuable to players refining tournament-ready lists, developers integrating Yu-Gi-Oh! data into apps, and organizers needing reproducible deck configurations. Unique value comes from deterministic exports, format-aware validation, and optional synergy scoring that prioritizes archetype cohesion. Core features include per-card data fields, deck-structure definitions, and strict rule enforcement. Use cases range from drafting a 40–60 card main deck, adding an extra deck, balancing sides, to exporting to .ydk for YGOPRO or to JSON/CSV for tooling. The system supports bulk imports, archetype tagging, and ban-list aware checks to prevent illegal configurations. Export formats are designed for reproducibility and interoperability in toolchains and tournament prep.

Frequently Asked Questions

Find Quick Answers

What formats are supported?

The tool validates decks against standard Yu-Gi-Oh! formats (TCG/OCG), enforces main deck sizing (40–60 cards) and ban-list constraints, and can export to YGOPRO (.ydk) as well as JSON or CSV for tooling.

Can I import existing decks from other tools?

Yes. The tool accepts bulk imports via CSV or JSON and supports copy-paste card lists, mapping names to card IDs and preserving quantities for quick deck recreation.

How is legality checked?

Legality is determined from the selected ban-list version, per-card copy limits, and deck structure rules. If a card is restricted in the active format, counts above the limit trigger validation errors.

What export formats are available?

Exports include YGOPRO .ydk for direct import into the game, plus JSON or CSV for external tooling and data analysis.
