so one way you can help maintain a haunted strat is using the Supportive super, it recovers 1 wound for each monster revived (meaning you actually heal 1 extra since the first was ignored from haunted)
pretty reliable until it isn't, mainly because since you'll be using the super to elongate the run rather than to save yourself from hard encounters, it's very likely that you get unlucky and just get squadwiped by 4 adepts anyways lol.
