I can see both "bant beanstalk" and "white beanstalk" in the data. Let me get both archetype overviews and then run all matchup winrates against the top 16 decks simultaneously.
White Beanstalk is the more prominent version. Now let me fire off all 16 matchup winrate queries at once.
Hey @JurgenKowalsky! Here are the White Beanstalk matchup winrates against the top 16 Legacy archetypes by meta presence over the last 60 days (draws excluded). Note: Bant Beanstalk had near-zero data and is effectively absent from the meta, so all figures are for White Beanstalk.
FAVORABLE MATCHUPS (above 50%)
UNFAVORABLE MATCHUPS (below 50%)
8. Lands: 40.0% (2-3, 5 decisive)
9. Aluren: 40.0% (2-3, 5 decisive)
10. Energy: 33.3% (2-4, 6 matches)
11. Doomsday: 28.6% (4-10, 14 matches)
12. Tron: 25.0% (1-3, 4 matches)
13. Blue Artifacts: 16.7% (1-5, 6 matches)
14. Grixis Reanimator: 14.3% (1-6, 7 matches)
15. Welder Combo: N/A (only 1 draw, no decisive matches)
The big takeaways: White Beanstalk demolishes fair blue and white midrange shells (Dimir Midrange at 92%, Death & Taxes at 100%), but struggles badly against fast combo and artifact-based strategies. Grixis Reanimator and Blue Artifacts are its worst matchups by a wide margin. Doomsday at 28.6% over 14 matches is the most reliable data point showing a genuine weakness against blue combo.
Important caveat: several matchups have small sample sizes (3-7 matches), so treat the extreme numbers (100%, 14.3%) with caution. The Dimir Tempo and Doomsday matchups have the most reliable data.
Sources: Data drawn from 31 Legacy tournaments (68% MTGO, 32% Melee) over the past 60 days.
