I'll analyze Affinity lists with and without these key cards in the maindeck over the last month. Let me start by getting the format ID and searching for the cards.
Now let me get the Affinity archetype overview and then query the database for detailed comparisons.
Now let me query the database to compare Affinity lists with and without Metallic Rebuke in the maindeck for the last month (August 29 - September 29, 2025).
Now let me do the same analysis for Weapons Manufacturing:
Let me calculate the confidence intervals using the Wilson score method:
Let me use a simpler approach for the confidence intervals:
Now let me get tournament sources for citations:
With Metallic Rebuke:
• Presence: 132 entries (85.2% of Affinity lists)
• Winrate: 49.7% ± 4.0% (95% CI: 45.7% - 53.7%)
• Sample: 614 total matches
Without Metallic Rebuke:
• Presence: 23 entries (14.8% of Affinity lists)
• Winrate: 60.6% ± 9.4% (95% CI: 51.2% - 70.0%)
• Sample: 104 total matches
Key Finding: Lists without Metallic Rebuke show +10.9% higher winrate, though with wider confidence intervals due to smaller sample size.
With Weapons Manufacturing:
• Presence: 30 entries (19.4% of Affinity lists)
• Winrate: 55.5% ± 7.8% (95% CI: 47.7% - 63.3%)
• Sample: 155 total matches
Without Weapons Manufacturing:
• Presence: 125 entries (80.6% of Affinity lists)
• Winrate: 50.1% ± 4.1% (95% CI: 46.0% - 54.2%)
• Sample: 563 total matches
Key Finding: Lists with Weapons Manufacturing show +5.4% higher winrate with reasonable confidence intervals.
• Metallic Rebuke is popular (85% adoption) but correlates with lower winrates
• Weapons Manufacturing is less common (19% adoption) but shows positive performance correlation
• Both findings suggest potential meta adaptation opportunities for Affinity pilots
