text: If the emblem’s ability causes a Vehicle to become an artifact creature, its base power and toughness will be set to 0/0. Crewing that Vehicle will not restore its power and toughness. Similarly, if the ability causes a permanent with station to become an artifact creature, putting an amount of charge counters on it greater than or equal to the amount required for it to become an artifact creature won’t overwrite the base power and toughness set by the emblem’s ability.
