Face pulls do an excellent job of bringing everything up top together. The rear delts get smoked, along with the upper traps, and they're a must-do movement for keeping the shoulders healthy.
The important part of face pull execution is that you get into external rotation. And make sure you're pulling to the face and not the neck. Maybe these would be performed correctly more often if they were called "forehead pulls" or "eyeball pulls," because that's the area you need to be shooting for. Do 4 sets of 12-15 reps.
Mike used to like Functional Training. He used to think Mike Mentzer was kind of a bonehead. Now he's not so sure about the former or the latter, along with a whole lot of other things. If his current rate of "unlearning" continues, he soon won't know anything!
