I had a situation with DarkJaguar and his ingenuity as usual. We had a match that we played where he had a star drop in at high altitude. So when turn 3 came around and they entered the central zone, he places the units overtop mine to land and rolled to stick. Now I called BS cause that's technically an attack and there was no way to show distance travelled to do collision damage. To his benefit though this is also technically an accidental collision as he was betting on scattering.
While I admire his frustrating creative ways around rules, can you clarify how damage is done if some one decides to do this? What if they actually do scatter onto a unit accidently?
