FREQUENTLY ASKED QUESTIONS
Is it worth opening HGSS Black Star Promos packs?
Based on current market prices, yes — the expected value is $40.65 per pack against a $4.99 pack cost, a positive return of +$35.66 on average. Keep in mind EV is a statistical average across many packs; individual packs vary significantly.

What is the best pull in HGSS Black Star Promos?
The highest expected-value card in HGSS Black Star Promos is Lugia, currently priced around $65.00. Chase cards like this drive most of a set's EV — a single pull can easily cover the cost of multiple packs.
How is pack expected value calculated?
Every booster pack contains a rare slot (one guaranteed rare or better) and a reverse holo slot (one random card from the set). We apply estimated pull rates to each rarity tier — Secret Rare ~4%, Ultra Rare ~7%, EX/V/ex ~14%, Holo Rare ~20%, Basic Rare ~55%. Within each tier, probability is split equally across all cards of that rarity. Each card's price is weighted by its pull probability and summed to produce the EV per pack. Pull rates are approximations based on community-verified data; actual rates vary by set print run and product type.
The HGSS Black Star Promos set was released on February 10, 2010 as part of the HeartGold & SoulSilver series, containing 25 cards across multiple rarity tiers. At a pack price of $4.99, the estimated expected value is $40.65 per pack — a positive return of +$35.66 on average.
