Extended art pull rates

Extended-art frame on legendary and chase cards. Across 42 collector booster products, the average expected rate is about 21.33 extended art cards per box (100% chance of at least one per box, roughly Every time).

Pull rates are computed from MTGJSON collector-booster collation (slot weights and pack configs). Treatment labels (Serialized, Surge foil, etc.) come from Scryfall. We dedupe chase cards duplicated into common showcase sheets and cap serialized-only slots at Wizards' published “<1% per pack” ceiling when multiple numbered cards share one slot. “1 in N boxes” uses a Poisson model: P(at least one per box) = 1 − e^−expected. Full methodology.
