Yu-Gi-Oh Deck Builder

The tool designs optimized Yu-Gi-Oh Master Duel decks under current banlists and card pools. It produces complete mains, extras, and side decks that respect the 40-card main deck and up to 15 cards in extra and side decks, with archetype and synergy considerations. Conceptually, it models a constrained selection problem: maximize synergy between chosen cards, meet legality constraints, and align with a target archetype or meta profile. It scores candidate builds using heuristic weights for consistency, resource pacing, and archetype fidelity, then filters results to produce export-ready lists. This yields rapid theorycraft gains for ladder play, tournament prep, and content creation. The tool is beneficial to players seeking repeatable build processes, coaches crafting meta reports, and creators generating reproducible deck summaries. Unique value comes from realignment to latest banlists, explicit support for archetype-driven filtering, and an easy export path for testing in Master Duel or documenting in guides. Core features include pool filtering, card-count enforcement, synergy scoring, and meta-fit evaluation, with optional budget and archetype constraints to tailor results to user needs. Use cases include constructing a pure sneaker archetype, adjusting a deck for budget limitations, or generating multiple variants for side-by-side testing.
