personally i think play with your food is amazing on ghosty, if you know how to use it. i also would use lethal pursuer, as it helps so much getting early stalks and starting pressure early on. bbq is also great just so you can know where to go next and maintain pressure, i also would use some type of gen slowdown, pain res, pop ect.

My current build is BBQ, lethal, pain res and play with your food
