Unstable Draft Booster expected value
The average is the sum of every card's price times its chance of showing up, so it counts the long-shot hits too. In this booster those long shots carry a lot of weight: the ten most valuable cards make up 53% of the average, which is why most packs come in below it. Expect about 1.11 rares and 0.18 mythic rares per pack.
| Pack worth at least | Chance |
|---|---|
| $10 | 9.0% |
| $25 | 2.6% |
| $50 | 2.0% |
| $100 | under 0.1% |
