Recently i have dicovered a problem while countering undead(never before).I play human and they try to avoid producing wizards,becouse they have nothing to do much to human wizards.Instead they produce fiends destroyers,due to their spell immunity and abominations.This hurts much to my nights and my wizards can`t do anything.To counter deystroyer i produce tanks but vs they die rather fast against that undead tactic.So please suggest a good strategy against this.
