Good, I have the top 16 archetypes and the Eldrazi archetype_id. Now let me get the matchup winrates for Eldrazi against each of the top 16 archetypes in that date range.
Here is Eldrazi's head-to-head record against the top 16 Legacy archetypes by meta presence over the last 60 days (2026-07-08 to 2026-09-07). Eldrazi's overall record sits at 52.38% winrate across all matches in the format.
Matchup breakdown (sorted by meta rank, wins-losses, WR%):
The clearest takeaways: Eldrazi performs well against the blue tempo/control shells (Dimir Tempo at 66.67%, Izzet Delver at 66.67%, Doomsday at 57.14%), which are the most-played decks in the format. On the flip side, it struggles against graveyard and prison strategies -- Grixis Reanimator is a near-unplayable matchup (0-3), and it is also negative vs. Death & Taxes, Lands, Azorius Midrange, and Show and Tell. Note that several matchups (Blue Artifacts, Welder Combo, Azorius Midrange, Grixis Reanimator) have very small sample sizes (1-3 matches), so treat those numbers with caution.
