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.

Hidden Arsenal: each 5-card pack has 1 Secret Rare and 4 Super Rares (Konami).
