I can see "Azorius Midrange" in the meta report which is the UW (White-Blue) midrange archetype. Let me resolve it and then pull all 16 matchups simultaneously.
Good, that's clearly a Legacy archetype (Force of Will, Brainstorm, Tundra, etc.) despite being tagged to pauper in the system. Let me also create the alias and then pull all 16 matchup winrates in parallel.
Here is the full UW Midrange (Azorius Midrange) matchup breakdown against the top 16 Legacy archetypes by meta presence, covering the last 60 days (2026-07-08 to 2026-09-07). All winrates exclude draws.
--- FAVORABLE MATCHUPS ---
vs Show and Tell: 76.47% (13-4, 17 matches)
vs Tron: 69.23% ( 9-4, 13 matches)
vs Dimir Midrange: 64.29% (18-10, 28 matches)
vs Aluren: 63.64% ( 7-4, 11 matches)

vs White Beanstalk: 28.57% ( 2-5, 7 matches)
The headline story is that UW Midrange has a strongly positive record against blue combo (Show and Tell at 76%, Tron at 69%, Grixis Reanimator at 56%) and rival blue midrange piles (Dimir Midrange at 64%), suggesting its permission suite and efficient threats are well-positioned against those strategies. The bad news is the two biggest problem matchups are against other fair decks: Dimir Tempo (38.8%, the format's most played archetype) and Lands (33.3%), both of which present angles UW struggles to address cleanly. White Beanstalk is also a rough one (28.6%), though the sample size there is small at just 7 matches. Death & Taxes also edges UW out slightly at 44.8%.
Note: some matchups (Tron, Aluren, White Beanstalk, Welder Combo) have relatively low match counts (7-13), so those figures should be read with some caution.
