Idea... hidden air sweeper
The idea of this is that is stays hidden until an air unit comes within range, then it proceeds to blow the air units to desired area.. this could be strategically placed outside a base and when someone spawns a healer, it would be able to say blow the healer within range of the air defenses or whatever. It would also make someone think twice about whether a spot might be occupied by a hidden tesla or a hidden air sweeper.
I also think the blowing distance/power should be increased by 1.. just my personal opinion.
