I'll analyze the matchup performance difference between Karn Eldrazi Ramp decks with and without Karn by examining Modern tournament data from April 2025 onwards.
Let me start by gathering information about the archetype and finding relevant card IDs:
Now let me query the database to analyze matchup performance for Eldrazi Ramp decks with vs without Karn from April 2025 onwards:
Now let me calculate the differential and get some additional context:
Based on the tournament data from April 2025 onwards, here's what the matchup analysis reveals:
Sample size: 177 Karn entries vs 596 Karn-less entries
• Azorius Control: 65.2% vs 43.9% (+21.3%) - Karn's wishboard access provides strong answers
• Samwise: 35.7% vs 62.5% - Actually worse with Karn (-26.8%)
• Tron: 53.3% vs 60.6% - Slightly worse with Karn (-7.3%)
• Domain Zoo: 33.3% vs 53.7% (-20.4%) - Karn versions significantly struggle
• Prowess: 37.7% vs 63.1% (-25.4%) - Massive disadvantage with Karn
• Boros Energy: 46.0% vs 54.7% (-8.7%) - Worse with Karn
• Samwise: 35.7% vs 62.5% (-26.8%) - Terrible with Karn
• Broodscale: 33.3% vs 50.0% (-16.7%) - Much worse with Karn
• Ruby Storm: 28.0% vs 46.8% (-18.8%) - Significantly worse
• Orzhov Blink: 44.4% vs 65.6% (-21.2%) - Much worse
• Living End: 22.2% vs 48.0% (-25.8%) - Terrible with Karn
• Affinity: 40.0% vs 51.5% (-11.5%) - Worse with Karn
Karn builds only excel against control decks (notably Azorius Control), where the wishboard provides flexible answers. However, Karn-less versions perform dramatically better against aggressive strategies (Prowess, Domain Zoo), combo (Ruby Storm, Living End, Broodscale), and midrange/blink strategies. The slower, more reactive Karn builds appear to struggle with the format's faster, more linear strategies.
