Open or Hold?
Opening loses money on average. Keep it sealed or buy the singles you want.
Low confidence estimate
91% of box price
Half of boxes do worse than this
We simulated 10,000 box openings using today's market prices. 8 in 10 boxes land between $28.86 and $101.52. Sealed, this box is up 20% from its $79.84 release price. Selling pulled cards costs roughly 13% in marketplace fees plus shipping, so real returns are lower.

A box has 16 packs of 12 cards. Pull rates aren't published by the maker, so we use community case-opening data. Every card of a rarity is treated as equally likely.
Rates per box: about 6 Super Rares, 1 one-star parallel, 2 Action Points, one 2-star parallel per 16-box case, and 3-star parallels at a few per hundred boxes. Every box includes one box topper.
English Union Arena pull data is thin (a few boxes plus Japanese data), so this is a rough guide.
Rare silver/gold box toppers and special-art Action Point cards are left out because nobody has published how often they appear, so this estimate may be a little low.
Bulk commons and uncommons are counted at 5¢ each.
