Wouldn't the Enforcer be reported as visiting two people? Also, I think if you're using the nurse in one setup, you should use it in both or in neither. The nurse can heal the tracker/cop with the risk of no report but can also roleblock the maf while enforcer/gf can claim blue. Interesting setup though.
Enforcer would, yeah, but they fake a double visit on someone else and say the same thing. Also Nurse roleblocking maf can be defended by the possibility of an nk. Because it's multi, you can use many different types of attack and defense as mafia (but you have to plan well ahead), and Town has to work together if they wanna solve the puzzle.
For me there are 2 ways to play the second setup as mafia- Either kill and nilla ccs Tracker or nk and Enforcer claims Nurse, so that the Tracker can't confirm literally anything.
