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 Unbroken Bonds set was released on May 3, 2019 as part of the Sun & Moon series, containing 234 cards across multiple rarity tiers. At a pack price of $4.99, the estimated expected value is $22.83 per pack — a positive return of +$17.84 on average.
