EX Hidden Legends Machamp is receiving errata for its "Brick Smash" attack to bring it in line with the Japanese version of the card. Weakness should be applied to the damage that Machamp deals. It should read, "This attack's damage isn't affected by Resistance, Poké-Powers, Poké-Bodies, or any other effects on the Defending Pokémon."
