Commanders

Share of Blue and more decks · each builder counts once

No commander changed clearly. Closest to a trend:

▲ Vraska, Soul of Stone 0.7% → 2.3% z = 2.1
▼ Emry, Lurker of the Loch 2.1% → 0.5% z = -2.1
▼ Ivy, Gleeful Spellthief 0.9% → 0.0% z = -1.9

Shares are out of the decks that can play the card. A change shows when it's clear: 10+ decks on one side and |z| ≥ 3, odds under 1 in 300 by chance. Cards first printed in Reality Fracture are under New cards by set.
