At least from my POV the point of perceived overpower card is the ToL buffed by the HoB. I am suggesting that the Force Hammer would be useful against the 9 Mana, 3 Armor, 8HP . Temple of Light. There is a chance you could one shot it.
If you decide that it is in your best interest to take it down, it is in your best interest to take it down as quickly as possible using as few actions as possible. Force Hammer fits the bill.
There of course are other options, move a middle level critter in to the zone of the ToL and buff with at Piercing Strike. That would be cheap mana wise.
All I am trying to say, is there are ways to take out ToL that are effective other than the action(s) lost.
