I think that you should get to load a Wizard Tower with each type of resource and each causes the Tower Wizard to cast different kinda of spells- Ex. 25 000 Gold=Chill (Slightly reduces enemy troops' DPS & Speed) or 25 000 Elixir=Enhanced Range, or 250 Dark Elixir=Engulf (Troops are set afire and take additional damage after hit, like Flanethrower in Boom Beach)
