Are these official pull rates?
These estimates use community sources and probability calculations.
These are modelled chances, not measured box or case odds. They assume random, unweighed packs and independent pack outcomes; factory collation can change the results. “1 in” is an average, not a guarantee.
Gold Stars use two sheet positions each with nine holo-sheet cards per 36 packs: about 1/242 per Gold Star. Foil Energy occupies the reverse slot; its odds remain unavailable. Independent pack calculations do not reproduce print-sheet collation.
