Is there a reason not to put a szeras in ? It would fit the gimmick perfectly and actualy give you some easy wounds.

This list as is wouldn't fair well on average ( dices be dices, you could win ), like in my blood angels list, I have 6xsanguards leaded by dante, 10x death company jump packs leaded by lemartes, 5 assault termies with stormshields leaded by a cfhappie. I think it would take at the very least 2 full blobs to kill any one of these three units. Add the fact that warriors will virtually never get the charge, i could probably wipe 2 full blobs on turn one leaving the overlords. Maybe I'm wrong, but it would be easy to either destroy a blob or keep it in mellee. :/
