HOW WE GOT THESE NUMBERS Methodology & data sources
Pull rates
Official Wizards of the Coast pack odds mapped to each slot's eligible card pool.
Price data
TCGplayer Market Price, refreshed daily. Market reflects closed sales, not active listings.
Median EV
Monte-Carlo simulation of 10,000 box opens, with pull-rate variance modeled per slot.
Outcome range
P25 / median / P75 from the same simulation. "Low" = a quarter of boxes open below it.
Serialized inserts
Excluded from EV. Their per-box odds are near zero and would distort the median.
