This is a one hit KO move which had a 30% chance to succeed if used against a Pokemon at an equal level to Machamp. In modern generations, Machamp has access to an ability called No Guard which allows for it to bypass accuracy checks entirely, so hypothetically this could have been a busted combo.

Pokemon obtained via the virtual council are actually locked to their hidden abilities, which in Machamp's case is steadfast.
