Data provenance and freshness

TCG AI SIM computes this page from persisted, AI-simulated RATING matches where both decks are Standard-legal. Rank is not a subjective tier or a leader-level rating: it is the position of this leader’s single highest-rated deck. Field and matchup win rates aggregate decisive appearances; mirror games are included in the field record, and opponent matchups require at least 20 games.
