I was thinking about how lazy I was and how tedious it is to duplicate something and move it across a map, and then I thought of a long-ranged duplicator.
For isntance, shoot a brick (which would work like the destructowand and have infinite range) and shoot another place and it will move the duplicated ghost brick there, then hit enter to place the brick/s you duplicated.
In layman's terms: Select brick to duplicate, shoot somewhere else to move the ghost brick (lazy and time-saving version of duplicator).
Also it doesn't have to be a gun exactly, I just mean a destructo-wand esque duplicator that you can move the ghost brick without using the numpad.
