Domain Zoo Winrate Analysis: With vs Without Fable of the Mirror-Breaker

Since the last set release (Edge of Eternities, August 1st, 2025), here's the performance comparison:

Without Fable of the Mirror-Breaker:

  • Winrate: 56.04% (CI: 45.84% - 66.24%)
  • 15 entries, 51-40 record (91 total games)

With Fable of the Mirror-Breaker:

  • Winrate: 48.35% (CI: 44.46% - 52.24%)
  • 130 entries, 307-328 record (635 total games)

Key Findings:

  • Zoo decks without Fable performed 7.69 percentage points better than those with it
  • However, the sample size for non-Fable decks is much smaller (15 vs 130 entries)
  • The confidence intervals overlap significantly, suggesting the difference may not be statistically significant
  • 89.7% of Domain Zoo decks are running Fable, making it nearly ubiquitous in the archetype

Statistical Note:

The wide confidence interval for non-Fable decks (45.84% - 66.24%) reflects the smaller sample size. While the point estimate favors non-Fable builds, more data would be needed to confirm statistical significance.
