KEY TAKEAWAYS:
The clearest signal cards are Sea Gate Oracle and Ephemerate. Not playing Sea Gate Oracle at all scores a dismal 39.6% over 85 entries, climbing steadily to a format-best 59.6% at 4 copies (small sample). Ephemerate at 0 copies is a brutal 30.6% over 28 entries, with 2-3 copies being the sweet spot (51.7-54.3%). Both reinforce that these are load-bearing engine pieces.
Ghostly Flicker shows a strong 1-copy is the near-universal correct choice (51.5% over 274 entries), while running 3+ collapses to 38.7% and 28.6%. Meeting of Minds at 3 copies (53.4%, 196 entries) and Mulldrifter at 3 copies (54.9%, 124 entries) both outperform their 4-copy variants. Murmuring Mystic at exactly 2 MD copies (51.3%, 275 entries) beats both 0 and 1-copy builds. For counters, 2 MD Prohibit (52.0%) and 1 MD Negate (54.1%) are the top-performing configurations. Sideboard Negate peaks at exactly 2 copies (54.4%, 221 entries), and SB Murmuring Mystic at 1 copy posts the highest SB mark (55.7%, 36 entries).
(*) = fewer than 10 entries; treat as directional only, not statistically reliable.
