Why we'd keep it sealed

Pull rates are still uncertain. The real value could be anywhere from €13 to €35.

How we work this out

We price every card at its Cardmarket 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.
