Right now: the best rip in Double Diamond is the Booster Box (24 packs) at $83.64 against $95.21 of expected pulls — a −3% margin after ~15% selling fees, and a 44% chance it actually pays for itself. Figures refresh every two hours.
Double Diamond is the Digimon Card Game main set from October 8, 2021: twelve-card packs, 24 to a box, a guaranteed Rare and one hit slot. It's an early set with a cheap median single and one genuinely expensive pull, which is the classic lottery profile: most packs pay back little, and the sealed price reflects everyone chasing the same card.
The hit slot pays a Super Rare about seven packs in ten, a Secret Rare roughly one in five and a Special one in ten. The chase is the Omnimon alternate-art Super Rare, priced far above anything else that comes out of a pack. The BeelStarmon alternate-art Secret Rare is the secondary target; the Alphamon Ghost Rare catalogued here carries the Xros Encounter label and isn't a Double Diamond pull.
Loose packs and the 24-pack box are both tracked. The loose pack models negative and the box hovers around break-even, with the Omnimon doing almost all the lifting; a box that misses it is a box that loses. Regional-champion cards and binder-set promos on the price list aren't pack pulls. Rates are community estimates. The live table below has the current fee-adjusted numbers.

FAQ
What are the chase cards in Double Diamond?
The Omnimon alternate-art Super Rare is the one card that matters, with the BeelStarmon alternate-art Secret Rare a distant second. The Alphamon Ghost Rare listed with the set carries the Xros Encounter label, and the Parasaurmon and Apemon champion cards are promos.
How many packs are in a Double Diamond booster box?
24 packs of twelve cards. Every pack has a guaranteed Rare and a hit slot that pays at least a Super Rare, with a Secret Rare about one pack in five and a Special about one in ten by community estimates.
Are Double Diamond pull rates official?
No. Bandai doesn't publish Digimon Card Game pull rates. The odds here are community estimates for the standard pack, and because one Super Rare dominates the set's value, the real-world spread around the EV is wide.
What are the odds a Booster Box (24 packs) of Double Diamond pays for itself?
About 44% after ~15% selling fees (60% before fees) as of 2026-10-27, computed from the exact outcome distribution of the Double Diamond pack model rather than a simulation. The median Booster Box (24 packs) returns $75.97 of cards after fees against its $83.64 price, and the chance of at least doubling your money is 1%. These odds refresh with every two-hourly price update.
