Avatar: The Last Airbender (856 decks), the first window

New cards by set

Cards first printed in the set · share of 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).

Deck shape by window

Per deck, except the deck count and shares

Each builder counts once per commander and set window, with their latest list. A deck counts in the window of its last edit.
