Estimated contents: nobody has published measured pull rates for this box yet, so we use those of boxes with the same pack layout. Treat the numbers as a rough guide.

Why we'd keep it sealed

The cards inside are worth $62 after selling costs. The box costs $160.

On average you lose $98 per box. Buying the singles you want is cheaper.

Pull rates are still uncertain. The real value could be anywhere from $38 to $119.

If you opened 100 boxes

  • 14 make money
  • 86 lose money

A typical box is worth $27. 1 in 10 boxes is worth $202 or more, and 1 in 10 is worth $14 or less.

The math, per box

From the price of every card to what you'd actually keep.

Pull rates we used

Where each number comes from, and how sure we are. Sources checked on 14 October 2026. This box's own pull rates haven't been measured, so these come from boxes with the same pack layout, with extra uncertainty added.

How we work this out

We price every card at its TCGplayer market value, take off the selling costs above, and open 100,000 virtual boxes slot by slot using the pull rates in the table. The verdict compares the cards with the box price and checks how often a box loses money.
