Good, now I have the archetype_id and format_id. Let me get the card_id for Stormchaser's Talent and then run the with/without analysis.
Now let me aggregate the with/without Stormchaser's Talent winrates from the entry-level data:
Here's the breakdown, @Zacktrack92:
In Standard, Izzet Lessons with Stormchaser's Talent in the main deck has a 52.4% winrate (3,200 W / 2,904 L) across 1,131 entries. Without it, the archetype posts a 52.2% winrate (1,182 W / 1,083 L) across 422 entries. The difference is essentially negligible: Talent versions edge out non-Talent versions by only 0.2 percentage points, a gap well within noise across this sample size. Talent is by far the majority choice (73% of all entries run it in the main deck), so it is clearly the de facto build, but the data does not show a meaningful performance advantage from running it versus not.
Both versions are hovering around the same 52% mark, suggesting the card is a natural fit for the archetype's game plan rather than a strict power-level upgrade over alternative builds.
