New cards by set

Cards first printed in the set · share of Izzet decks that can play them

Star Trek starts Nov 16. Decks built with its cards before then count in Reality Fracture, so these are early brews.

– means fewer than 3 decks. Picked up later: the share clearly rose after the release window (10+ decks, |z| ≥ 3).

▲ Ral, Monsoon Mage // Ral, Leyline Prodigy 4.9% → 6.9% z = 0.6

▼ Spider-Man 2099 18.4% → 15.3% z = -0.5
