🧬 Cosmo Fling vs. Top 5 Modern Decks

(Jul 15 – Sep 14, 2026 | Overall winrate: 46.0%)

Key Takeaways:

• ✅ Affinity is a standout target — Cosmo Fling goes 72.7% in 22 matches, likely because the combo outraces artifact synergies
• ⚠️ Broodscale & Prowess are near-even but slightly unfavorable — likely dependent on who goes first and disruption density
• ❌ Esper Blink is rough at 20% — the interaction-heavy playstyle of Esper likely dismantles the combo setup
• 💀 Goryo Reanimator is a near-nightmare at 12.5% — both are racing combo decks but Goryo appears significantly faster or more resilient (3–21 in 24 matches)

Note: Esper Blink and Goryo sample sizes are smaller (11 and 24 matches respectively), so take those numbers with a grain of salt. Broodscale and Prowess have more robust samples.
