I'll analyze the performance difference between Affinity decks running Metallic Rebuke in the main deck versus those that don't. Let me gather the data.
Now let me check the performance of Affinity decks with and without Metallic Rebuke in the main deck over the last 60 days.
Let me also check how prevalent Metallic Rebuke is in Affinity main decks during this period:
Now let me get some sources to support this analysis:
Based on tournament data from the last 60 days, Affinity decks WITHOUT Metallic Rebuke in the main deck are performing better than those with it. Decks running Metallic Rebuke main averaged a 46.0% winrate (207-243 record) across 106 entries, while decks not running it achieved a 53.7% winrate (51-44 record) across 29 entries.
Metallic Rebuke appears in 78.5% of Affinity main decks (106 of 135 total entries), making it a popular inclusion with an average of 3.24 copies per deck when played. However, the performance data suggests that the counterspell may not be providing the expected value in the current meta environment.
The sample size for non-Rebuke builds is smaller (29 entries vs 106), but the 7.7 percentage point winrate difference is substantial enough to suggest that current Affinity builds might benefit from reconsidering their main deck counterspell package.
