Commanders

Share of decks · each builder counts once

No commander changed clearly. Closest to a trend:

▲ Narset, Jeskai Waymaster 0.0% → 0.7% z = 2.4
▲ Ezio Auditore da Firenze 0.2% → 1.1% z = 2.2
▲ Urtet, Remnant of Memnarch 0.1% → 0.8% z = 2.1

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 Lorwyn Eclipsed are under New cards by set.
