I have just started painting the Viks and have added a few extra merc models
I think the dreamer and co would be difficult to beat up on ( remember you dont have to kill any of the enemy to win) and from what I have read the only reliable way to get the buggers are to support your crew space them approx 3"-6" apart and in support of each other and try to get the dreamers stuff on the counterattack firing into combats if you need to.
good luck
just finished my first malifaux mini, the sword Vik and yes you do need patience but the end result is cool. My wife and daughter gave the thumbs up so Im happy
daughter loved the puppet deck to
