I'm playing machina vs spawn and came up with a nifty little gotcha - one of my hunter scouts was in trouble, being chased by some buzzers. I ran him back to a XT firing line and the buzzer on pursue-and-chew got smartly shot dead.
Which leads to the idea... fix him up and send him out on retreat on sighting. Anything that chases him will get drawn into the guns.
When that stops working I could send him out on stop and shoot orders for an easy kill or two .
Sadly I think my opponent has figured all this out already.
