I have a unit I want to disguise as a bush, the only problem is that he will still belong to me so any units that happen to pass by will automatically attack it. Then I remembered the mechanical critter item, which I think made a critter that belonged to you but wouldn't come under attack from any enemy units it passed by unless a player specifically targeted it. How do I make my unit act the same way so that no one auto-attacks it unless a plyter actually realizes it and forces attack himself?
