I found Nadu data, but it's showing as Modern format rather than Legacy. Let me check if there's a Legacy Nadu archetype specifically.
Great! I found Legacy Nadu. Now let me get the specific winrate for Legacy Nadu over the last 60 days.
Legacy Nadu has a 53.7% winrate over the last two months, going 122-105 in non-mirror matches across 244 games. This represents a solid but not dominant performance in the format.
The deck has been consistently active in the meta, appearing regularly in both MTGO challenges and paper tournaments. Nadu's moderate success suggests it's a viable competitive option but faces meaningful resistance from the Legacy field.

Based on the last 15 days of Modern tournament data, Affinity has struggled overall with a 42.03% winrate. However, there are clear performance differences between builds.
The Base Kappa Cannoneer build (without Thought Monitor) performed best with a 58.33% winrate across 5 entries, compared to the more common Thought Monitor build at 51.64% across 29 entries. The traditional creature-based variants like Reality Forger and Nettlecyst builds appear to be absent from recent competitive play.
Affinity currently represents 4.93% of the Modern meta, placing it 4th in presence but significantly underperforming tier 1 decks. The streamlined Kappa build's superior performance suggests players should consider cutting Thought Monitor for more focused artifact synergies, though the sample size is still relatively small.
