I'll analyze Dimir Midrange in Standard, comparing the performance of decks running Flitterwing Nuisance versus Spyglass Siren.
Now let me query the database to analyze the performance split between decks running each card:
Now let me get matchup data for both deck types against common opponents:
I'm seeing an issue with the match result data showing all zeros. Let me check the match data more carefully:
Let me check what the actual result values look like in the matches table:
Ah, the result values are 'WIN', 'LOSS', 'DRAW' not 'W', 'L', 'D'. Let me fix the queries:
Now let me get sources for context:
Dimir Midrange in Standard shows a clear performance difference between the two one-drop options. Spyglass Siren builds are the overwhelming favorite with 2,645 entries achieving a 50.9% winrate, while Flitterwing Nuisance builds have only 64 entries at 48.9% winrate. The data heavily supports Spyglass Siren as the superior choice.
Looking at matchup spreads, Spyglass builds show better consistency across the field. Against Izzet Cauldron, the format's most-played matchup, Spyglass posts 41.8% across 2,122 matches. Against Jeskai Control and Azorius Control, Spyglass performs excellently at 61.2% and 60.7% respectively. The card enables stronger control matchups and holds steady against aggro (50.6% versus Mono Red Aggro across 1,573 matches).
Flitterwing Nuisance builds have limited data but show some interesting spikes: 60.8% against Izzet Lessons and 61.9% against Reanimator. However, they struggle badly against Jeskai Control at 30.8% and underperform against Simic Cub at 43.9%. The sample size difference is massive - Spyglass has 40x more entries, making it the established, proven choice. Flitterwing appears to be an experimental option that hasn't gained traction.
