Brock's Pewter City Gym (sm115-54) is a Stadium Trainer card from the Hidden Fates expansion. While in play, it reduces damage dealt to all Onix-GX by 40 after Weakness and Resistance are applied. The card remains in play until another Stadium replaces it, and you cannot play it if one with the same name is already active.
