The Jeskai Control result came back as Pioneer, not Modern. Let me check if there's a Modern Jeskai Control archetype and pull winrates and card data for the 60-day window.
Good. I can see "jeskai control" exists in Modern with ID b4838de5. Now let me get its winrate and also do the performance split for Azorius Control with vs without Day's Undoing and Narset.
The WITH...SELECT queries were blocked. Let me restructure them as simpler subqueries.
The match result queries returned 0 wins/losses because the match result field must use different values. Let me check the matches schema and fix the query.
Now let me get sources to cite.
Here is the full breakdown for @redsizzl, looking at Modern over the last 60 days (May 22 - July 21, 2026):
Variant Summary (245 total Azorius Control entries, mirror-excluded):
The plain Azorius build without the Day's Undoing/Narset combo is the clear winner by the numbers. The "lock" variant (Narset + Day's Undoing, which prevents opponents from drawing cards during Undoing's trigger) underperforms by about 4 percentage points against non-mirror opponents. It is worth noting that both Day's Undoing (43.3% presence) and Narset (45.3% presence) are not majority-played cards in the archetype, so the split is meaningful: the majority of Azorius pilots have organically converged on the non-combo build.
Jeskai Control in Modern has an extremely thin sample over this period (only 7 non-mirror matches), so any comparison there is unreliable. The archetype barely registers in the field right now, and what little data exists is negative. For competitive play, the conventional Azorius list without the Narset/Undoing package is the best-performing control variant by a meaningful margin.
