Aren't you thinking of Black Faith here? They have what you want: cheap forgers (especially cheap because of lower upkeep), and a full random. That comes at the cost of a slower research, and a more expensive theme, as you cannot go all the way to Drain 3 without taking "damage". If you are lucky, you can create a research pocket though, by using a Stone Idol, hence solving Drain problems with Black Faith.
Taking Earth on the Pretender is advised however, in case all your mages agree not to have an Earth random.
Still, you will recruit lots of them, so 1/8 should happen sooner or later.
