Heavy armor is reliable when i first get a golem out, then when its like 11/11 or out of that one hit from a lightning bolt ill rage it. Its more reliable than chaos power simply because you can still get CC'ed cause of it. Silence stops your opponent in his tracks, if you ever been silence by a rush deck on turn one youd realize how bad off a well timed silence is for an opponent.
And besides maybe fire towers, what else would i would i put in my deck that isnt already there. I already got 6 golems, 4 minors, 2 dragons, and rols are fodders, i dont see a real difference in fodders if im just gonna fodder them off.
