Core Set 2021 Collector 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. The ten most valuable cards make up 20% of it, so the value is spread across the pack rather than resting on one big hit. Expect about 3.58 rares and 0.99 mythic rares per pack.
