Cygnar Stormwall Colossus Stat Card

[Stuart]

Your question's answer; with no Spd and no Movement abilities it looks like they're static and can only be replaced if you remove one first. A clever opponent would leave them be, limiting your ability to place new ones unless you destroy it yourself. On the other hand they are fantastic denial models if you place them around an objective.

Ah, I getcha - cheers Si!
