Good catchers can do this. He takes a couple fastballs, then we come back with a slider to strike him out. Two fastballs freeze him, because he's looking for a slider. Now he's looking for the fastball. Sweat strikes him out with a slider.
Purists grasp the concept.
Casual fans run for the remote. Catcher calls a pitch. Pitcher throws it. It works, or it doesn't. It's not an art form.
