I'll need to gather the Pioneer meta data first, then filter for MTGO sources. Let me start with the meta report!
Now I have the top 10 most played archetypes. Let me get their archetype IDs and then filter for MTGO-only data. I'll fetch all archetype overviews in parallel to get their IDs.
Now I have the archetype IDs. Note that some archetypes (izzet prowess, golgari midrange, azorius control) returned IDs for the wrong format (standard/legacy/modern). I need to get the correct Pioneer IDs for those. Let me now run a custom MTGO-only query for all 10 archetypes using their correct Pioneer IDs.
No results ā the source field value might differ. Let me check what sources are available in Pioneer tournaments.
Source is uppercase MTGO. Now let me also get the correct Pioneer archetype IDs for izzet prowess, golgari midrange, and azorius control, and run the full MTGO-only query.
Here are the results, MTGO-only, for the top 10 most played Pioneer archetypes (Jan 22 ā Mar 23, 2026):

š„ Azorius Control is the highest winrate deck among the top 10 most played archetypes on MTGO at 56.64% (243Wā186L across 99 entries). Notably, it achieves this despite being only the 6th most played deck, suggesting it's somewhat underplayed relative to its performance. Mono Red Aggro, despite being the 2nd most played deck, has the worst winrate at just 45.19%.
