I have never found it to be a dead draw, and was curious as to this
So you have never drawn the berserk in your first hand, or early game at all? It's not played main because It doesn't need to be played main, when your going to kill with tog, you have a bunch of cards, and enough protection where you can just wish for it, rather then using one in your mainboard, while yes, mainboard berserk can often be easier, it's not more important then whatever else you could be playing, it's just simply not needed in the maindeck of hulk....
