What problem does it solve? Before building or reviewing a Yu-Gi-Oh! deck, players need to understand an archetype's playstyle, core cards, and meta position, but this information is scattered across local YDK files, tournament results, and community discussions. ## Core Features & Use Cases - Reference Gathering: Searches local YDK deck files by filename and card content, runs consensus analysis with ydkshow.py, and collects online sources like tournament results, tier lists, and community discussions. - Deck Classification: Classifies archetypes as Control, Combo/Expand, or OTK using measurable criteria such as trap counts, extra deck monsters, and search chain length. - Core Card Extraction: Identifies core cards from consensus statistics and online decklist frequency, verifying series membership via setcode matching. - Use Case: Before building a Swordsoul deck, run this workflow to gather recent top-cut decklists, classify the deck type, extract its core cards, and summarize its current tier placement and key variants. ## Quick Start Research the Swordsoul archetype and classify its deck type, core cards, and current meta position.
