Two I've done recently.
Windrunner + Nature's Prophet.
Prophet throws down trees surround, guaranteed shackleshot.
Faceless Void + Enchantress.
Usually easier during team fights but still viable during laning, Void's Chronosphere with Enchantress at the range for her impetus to do max damage is truly a amazing thing. This becomes almost a guaranteed double kill during mid/late game team fights where Enchantress with Scepter can easily target whoever was unlucky enough to get caught in the Chronosphere that isn't being attacked by Void.
