Master Ball Mirror Pull Odds Per box : Exactly 1 Master Ball mirror card Total pool : 153 possible cards Odds of pulling a specific card : 1 in 153 boxes (~6.3M / ~$43,000) Odds of pulling a top-10 Master Ball : 10 in 153 (~6.5% per box) Odds of pulling Gengar OR Pikachu : 2 in 153 (~1.3% per box) This extreme scarcity is why the top Master Ball mirrors command prices that rival or exceed the sets Special Art Rares and why the Japanese version has no true equivalent in the English TCG
