I get Modern Challenge winrate data from multiple sources, accessed through the tournament database. Let me show you what's available:
My Modern Challenge winrate data comes from:
Primary Source: MTGO (Magic Online)
Secondary Source: Melee
Total Dataset:
The database tracks every match result (win/loss/draw) for each entry, allowing me to calculate:
The data is sourced from official MTGO Challenge results published by Wizards, which include complete decklists and standings. This gives me the most comprehensive and reliable dataset for competitive Modern play.
Note: Winrate calculations exclude draws by default (draws don't meaningfully contribute to win percentage), and I can filter out mirror matches to show true cross-archetype performance.
