Head-to-Head Matchups

Winrates vs every other archetype, sorted by the opponent's field share. Mirrors excluded. Shrunk WR uses a Beta(2, 2) prior so a 1-0 cell doesn't read as 100%; it feeds the EV calc above. Adj WR is the skill-controlled view: derived from per-match ELO deltas (0.5 + avg ELO Δ / K=32, same shrinkage), so it tells you what would have happened on equal-rating play. A faded Raw WR means under 10 matches — lean on the Shrunk WR column there.

Mirror Analysis

In 1 mirror match, here are the card-count differences that most often separated the winning deck from the losing one. Staples (cards both decks run at the same count) are filtered out — only flex slots show up below. Cards whose count only differed in fewer than 3 mirrors are also held back as too sparse to call a pattern (still visible in the raw table further down). Small sample warning: 1 mirror is borderline; treat these as suggestive, not conclusive.

No card differed in at least 3 of the 1 mirror we have. The raw table below has the sparse signals that didn't clear the threshold — treat them as noise unless the sample grows.

Show all 15 cards with non-zero signal (raw numbers, including 15 held back from the grid above)
