I'd be happy to help you identify the best performing deck! To provide you with accurate data-driven analysis, I need a bit more information:
Which format are you interested in? (Modern, Legacy, Pioneer, Standard, Pauper, or Vintage)
What time period should I analyze? (e.g., "last 30 days", "since the latest ban", or a specific date range)
How do you define "best"? For example:
Once you provide these details, I can query the tournament database to give you concrete data on which deck is performing best according to your criteria, along with supporting statistics and recent tournament sources.
