Structure: 24 packs × 14 cards (7C/3U/2 rare-slot); epic replaces a rare ~1-in-4 packs, alt art ~1-in-12, secrets/SP ~1-in-72. Community-observed rates (cardgamer, TechRaptor, Harlequins) — Riot publishes no official collation. Specific-card odds assume uniform collation within a tier; EV is an average over many boxes, not a promise about yours.
