How to pull Brock
In a Gym Heroes pack, the Rare slot shows a Rare Holo card about 33.3% of the time. In other words, about one Gym Heroes pack in 3 lands a Rare Holo card in that slot. Brock is one of 19 priced Rare Holo cards in Gym Heroes that can fill that result, so landing this exact card is less likely than the rarity figure. These are the published odds for Gym Heroes: the full slot-by-slot table is on the Gym Heroes page, and the odds page explains how each set's rates are built. Every Gym Heroes box commits its card order before the first pack is sold, so each rip can be checked once the box sells out.
