Not going to get into all the different timelines, but in the original Pre-Crisis JLofA, not long after Zatanna changed her look from the Dick Dillin ponytail costume to the George Perez costume used in IC, Zatanna's powers had been reduced to only working with the elements of fire, water, etc... She no longer could just conjure things out of thin air or mind-wipe anyone. Her powers were much more limited by that point.
