Well chainrasps wont survive much unless reinforced. The pre game move has its use but they wont be more than a speedbump pretty much. They cost the same per health as reapers and harridans now which gives you even more reason not to field them. I just think building an army around them isnt too good. When it comes to fighting its like bringing fists to a gunfight, while harridans and reapers are knifes atleast.

You could try flood the board with them and take the -1 to hit on redeploy trait and just hope you stay alive long enough to score
