The Secret Forces - Booster Box

Is a booster box of THSF worth opening?

Box price$332Cardmarket, converted to dollars
Expected value$93.06
If you sell the cards$67.40With a 5% fee and leaving out cards under $0.50
A typical box$65.46The median of 10,000 simulated boxes
You get your money back0.0%Almost never

On average, no: selling the cards from a THSF box would get you $67.40, 20% of the $332 it costs. A typical box gives $65.46 and only 0.0% of boxes get your money back. If you're after a specific card, buying it as a single is usually cheaper.

How reliable the rates are: good (several sources that agree).

THSF pull rates

How many cards of each rarity group come in a 24-pack box, how many packs it takes to pull one specific card of the group and how much the group adds to the box value.

The cards that carry the box

What weighs most in the expected value: expensive cards that are hard to pull.

Where the numbers come from

The expected value adds up, for each rarity group, the copies in a box times the average price of its cards (the English card, with its TCGplayer price or, if there isn't one, Cardmarket's converted). The simulation opens 10,000 boxes with the same rates.

All-foil 5-card set: 4 Super Rares and 1 Secret Rare per pack (Konami).
