Tournament Lab combines event-specific metagame forecasting with Monte Carlo tournament simulation so players can estimate the field they are likely to face and compare how legal archetypes are positioned. Forecasts use recent tournament history, geography, expected attendance, matchup data, and uncertainty rather than treating every event as the same global metagame.
Forecast the expected archetype field for upcoming Standard events with uncertainty ranges instead of a single fixed share.
Simulate Swiss rounds, Day 2 cuts, and top cut using historical archetype matchup probabilities and event structure.
Compare each archetype's probability of reaching Top 8, winning the event, or achieving a selected finish target.
Test different field sizes and sample forecast uncertainty to see how sensitive deck choice is to metagame assumptions.
Use the results as a decision aid for tournament preparation while keeping experimental model uncertainty visible.
