Open or Hold?
Opening loses money on average. Keep it sealed or buy the singles you want.
Low confidence estimate
90% 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 $18.52 and $106.17. Sealed, this box is up 30% from its $79.84 release price. Selling pulled cards costs roughly 13% in marketplace fees plus shipping, so real returns are lower.
| Pull | Per box | Avg card | Adds to box | Best card |
|---|---|---|---|---|
| 3-star parallel | 1 in 50 | $1,500.00 | $30.00 | Rem (053) (SR***) · $1,500.00 |
| 2-star parallel | 1 in 16 | $373.01 | $23.31 | Rem (019) (SR**) · $417.07 |
| 1-star parallel | 1 | $16.46 | $16.46 | Let's Start Here, From Square One. No... From Zero! (U*) · $67.18 |
| Super Rare | 6 | $1.94 | $11.63 | Rem (019) · $7.22 |
| Common | 120 | $0.05 | $5.45 | Puck (001) · $0.05 |
| Uncommon | 48 | $0.05 | $2.32 | Ram (009) · $0.05 |
| Rare | 10 | $0.17 | $1.69 | Puck (002) · $0.23 |
| Action Point | 2 | $0.66 | $1.33 | Action Point Card (AP02) · $0.89 |
| Box topper | 1 | $1.13 | $1.13 | Echidna (091) (Box Topper Foil) · $1.76 |
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.
