where do you get your modern challenge winrate data

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)

  • 488 Challenges tracked (99.6% of all Challenge data)
  • 15,616 deck entries with full match records
  • Coverage from November 2024 to present (October 13, 2025)
  • All weekly Modern Challenges (Saturdays/Sundays) with complete decklists and round-by-round results

Secondary Source: Melee

  • 2 Challenges (paper events)
  • Limited coverage from mid-2024 to August 2025

Total Dataset:

  • 490 Modern Challenges
  • 15,658 unique deck entries
  • 62,516 individual matches recorded

The database tracks every match result (win/loss/draw) for each entry, allowing me to calculate:

  • Overall archetype winrates
  • Head-to-head matchup statistics
  • Performance trends over time
  • Mirror match data (can be excluded from calculations)

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.
