Curated star-player insert (Zion Williamson, Luka Doncic, LeBron James, Giannis Antetokounmpo, etc.), randomly inserted per hobby box on average. Count of 20 confirmed identically by cardboardconnection, checklistcenter, and tcdb's full card-level checklist (all three list the same 20 players). No manufacturer print run or numeric pull-rate odds published anywhere found; a third-party analytics site (130point) derives an unofficial "1 per case" estimate reverse-engineered from checklist/population data with an explicit disclaimer that its figures "should not be considered authoritative in any way" and are not sourced from Panini -- not usable as stated odds per spec (never infer odds from print run). Marketplace/eBay listings label individual Downtown cards "Case Hit SSP" but this is marketplace copy, not manufacturer- stated odds, and per spec is not usable to tier -- not tiered in the scarcity pass (see scarcity_sets.csv).
