Hmmm... yes, Magma would be the obvious counter; but (and this is a big but) the "hum hum" uses Mistform AND Storm in conjunction. This effectively renders any range depending spell unusable.

So yes, more steel on top of the mountain of steel my warriors already possess may be a valid tactic, just too bad that they can't hit squat and of course decides to take a nap after a while in combat.
