How these numbers are made
print-sheet odds (MTGJSON) · confidence high. The pack variants and per-card sheet weights compiled from Wizards' collation information, as published by MTGJSON. Sources: magic.wizards.com.
The average is exact — every card's price times how often it appears. Median, the top-10% figure and the hit rate come from 2,000 simulated packs, the same packs every night, so the numbers move only when prices move.
