@ Razhem... we play with pretty much terrain on baord... using a mix of terraclips and mortheim buildings for the most... you could get an impression in the pictures of my armyproject. it's on a differnt board an in german tough!
Or if we play at the club the amount of terrain is like this
Copycat didn't do much... i just happen to like the model and painted it recently... so i snugged him into the lists. (and i didn't have have the Avatar for Seamus at that time.)
All the above lists are based on what i had available in my modelpool at that time. So it's not strictly "the hardest you can get!"
For sure you can get into trouble with the Betelist against Nonliving or Construct heavy builds. But on the other hand: just don't take the list. Malifaux is all about rock-scissor-paper.
For Seamus: he ist tough, has his gun and a damagespell that heals him plus some nasty CC Triggers paired with Terrifying. Plus Use Soulstone, so that might not be the end of the line concerning damage but at least it's decent enough as far as i see it for no hiring costs.
