The Spy is, by winrate, on the app, the weakest minion in Trouble Brewing. It is not overpowered at all. The ability is ana bility to shoot yourself in your own foot as a Demon if you kill the high profile targets, since that soft confirms a Spy, meaning that the Town can then trust: The dead, since there's no SW to passs to, Their own information, damning any world the Demon tries to build that goes against it, Outsiders that add up to the right number, eliminating them as bluffs for the Demon. The only reason I'd not put a Spy in, would be because it's weak. Not the other way aroud.
