📊 Key Takeaways

• 🚨 Boros Energy is a nightmare — 1-5 (16.7%) vs the #1 deck in the format. This is the deck's biggest problem given Energy's 21% meta share.
• ✅ Big mana/ramp matchups look excellent — Amulet Titan and Tron both 100%, suggesting the combo is fast enough to race them.
• ⚠️ Sample sizes are very small — most matchups have only 1-3 games. The "100%" WRs should be taken with a grain of salt.
• 📉 The deck's 40.5% recent tournament WR (from overview) vs 56.7% match WR suggests it's exiting early in events but winning matches when it does play.
