Pro Deck Builder

Pro Deck Builder is a domain-focused tool for Yu-Gi-Oh players, coaches, and content creators to model deck composition, evaluate synergy, and enforce game rules. It treats deck construction as a constrained optimization problem, incorporating deck size, archetype requirements, card limits, and the current banlist to ensure valid output. By coding each card with attributes such as type, attribute, level or rank, and archetype tags, the system can assess how well a candidate deck aligns with a target plan and compare many alternatives quickly and reproducibly.
It translates domain logic into a structured workflow: define a card pool and constraints, specify target archetypes or synergy goals, input available cards and limits, and run optimization to identify high-scoring combinations. The scoring function combines archetype fit, synergy weights, consistency, and risk flags, while feasibility checks ensure adherence to banlists and format rules. Outputs include a recommended decklist, rationale for card choices, and notes on matchup considerations.
Benefits include faster iteration for tournament prep, objective comparison between candidates, and reproducible results for coaching and content creation. Unique differentiators are explicit constraint modeling, transparent scoring with explainable decisions, and support for side decks and format variations. Use cases cover starting deck design, meta adaptation, budget-limited pools, sideboard planning, and scenario testing for hypothetical cards or banlist changes.
