If your opponent is being that static id just use turn one to move into position and start throwing Ice Pillars any direction you think his "main" crew would be heading. Raspy and the Wendigo can effectively quarantine a good section of most tables. If you deploy second and can get within reach, a December acolyte can focus, harpoon gun and cheat the severe to just remove the Wretch as well.
Against the Viks specifically, id also make sure you have your models in range of a sub zero upgrade. Chances are youre going to be charged at some point, but at least this way you can limit your opponent to just the one attack action.
