FREQUENTLY ASKED QUESTIONS
Is it worth opening Delta Species packs?
Based on current market prices, yes — the expected value is $124.07 per pack against a $4.99 pack cost, a positive return of +$119.08 on average. Keep in mind EV is a statistical average across many packs; individual packs vary significantly.

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 Delta Species set was released on October 31, 2005 as part of the EX series, containing 114 cards across multiple rarity tiers. At a pack price of $4.99, the estimated expected value is $124.07 per pack — a positive return of +$119.08 on average.
