Deck Builder AI

The MTG-focused deck-building tool provides a disciplined, repeatable workflow for designing, evaluating, and refining Magic: The Gathering decks under user-defined constraints. It is intended for competitive players, coaches, content creators, and serious hobbyists who want transparent decision-making, auditable step-by-step reasoning, and the ability to compare multiple archetypes side by side without manual trial-and-error.
Conceptually, the tool treats a deck as a structured set of cards with attributes such as name, mana cost, color identity, rarity, and synergy signals. Users specify deck_size, allowed_sets, format legality, and a budget. The engine searches the card pool, evaluates combinations against goals like mana stability, curve distribution, color balance, and win conditions, and returns a ranked set of candidate decks with explanations.
Core differentiators include constraint-aware optimization, reproducible exports, and interpretable scoring. Advanced options enable synergy scoring, curve shaping, sideboard tailoring, and draft presets. It supports scenario planning (e.g., present meta constraints or budget limits) and provides evidence-based rationale for each recommendation. This helps teams plan experiments, streamlines content creation, and reduces guesswork in deck design.
Typical use cases include preparing tournament-ready 60-card lists, testing alternative archetypes within budget or set restrictions, and generating renderable deck lists for articles or streams. Outputs include a ranked deck list, associated mana curve, total cost, and a concise justification that can accompany public postings.
