YGOPRO Deck Builder

YGOPRO Deck Builder enables precise construction and validation of Yu-Gi-Oh! decks for the YGOPRO platform. It integrates a card database to assemble main, extra, and side decks under strict rules (deck size, legality, archetype alignment). The system supports constraint-driven workflow: users specify limits, allowed archetypes, sets, and ban lists; the tool then generates candidate decks that satisfy those constraints. Multiple profiles can be tested, and results are exportable in machine-friendly (CSV/JSON) and human-readable formats for testing and sharing. Conceptually, the tool treats deck-building as a constrained optimization problem, where each card contributes to a score based on archetype fit, synergy, and resource curves; the highest-scoring decks are surfaced. Use cases include meta-testing, content creation, and practice for tournaments. The tool focuses on data-centric deck construction, not in-game visualization or sleeves, and emphasizes reproducibility by parameterizing constraints and allowing export of exact card lists. Unique value lies in its combination of legality-aware filtering, archetype-aware scoring, and flexible export options that streamline iterative deck refinement across different playstyles and formats.
