If you're just poking around in random places you'll probably never find any wizards. It's not as though in any reasonably realistic scenario the 20th-level wizard is out on a random road going from one random place to another.What you want to know?
He's hunting hidden until I find an unhappy Wizard around

So is any simulacrum of anyone other than the caster.
So is anything you've cast Planar Binding on, especially since you don't have any way to bring them to yourself.
