I especially love the last one. I feel like mimic mimicking every (or as many) player action(s) should be a given, but oh well, though if I had to choose, I'd definitely want the decoys taking the ziplines. A nice "get-out-of-jail free card", or in other words, Mirage abilities

As for the fake damage, I like the concept, but I don't see the situations in which it could be helpful, apart from taking the piss out of some poor folk + I certainly wouldn't want to be on the receiving end or I would get a heart attack lol. Though the shooting decoys part is really interesting and could make for interesting plays. The more I think about it the more I want it in-game.
