He would actually move faster than any other champion while out of combat, as long as he was travelling at least 400 units with each tunnel. This is because tunneling has a cooldown of one second, and it would take him exactly 1 second to travel 400 units. Which means that he would have a constant movement speed of 400 while out of combat, not including bonuses.

Ultimate would be used for escapes, general mobility, and quickly laying damage trails.

Speaking of damage trails, it would be difficult to chase him, as the pursuers would always be slowed and take constant damage while following him. The general idea of this champion is to constantly be moving, thus constantly be laying damage trails. All but one of his abilities are focused on movement and the ability to kite, and being punished when caught.

As for ganking, map awareness would be key when playing this champion.
