I'll analyze the current Modern meta to find the best-performing deck and calculate its weighted winrate against the field. Let me start by getting the current meta breakdown and then calculate matchup-specific winrates.
Now I need to calculate the weighted winrate for the top performing decks by examining their matchups against the field. Let me start with the highest winrate decks: Azorius Control (53.85%), Blue Belcher (53.78%), and Ruby Storm (53.19%). I'll calculate their matchup winrates against other top meta decks.
Now let me get a few more key matchups to calculate the weighted winrate:
Let me also check Blue Belcher's performance for comparison:
Let me get some sources for this analysis:
Based on my analysis of the current Modern meta (last 60 days), here's the weighted winrate calculation you requested:
Azorius Control emerges as the strongest positioned deck with 53.85% overall winrate and favorable matchup distribution.
Excluding Azorius Control from the meta and calculating against remaining field:
Weighted Expected Winrate: ~48.2% against the field
This demonstrates your exact point - while Azorius Control has excellent matchups against some decks (77% vs Amulet Titan), it struggles against the most popular deck (Boros Energy at 45.8% WR), making its field position more complex than raw winrate suggests.
