It's great. I used it with EA C'tis.
It can take out ANY province, knights, barbarians... anything, right from the start.
I used E4S6. Once you research buffs like luck, body.e. earth power and teleport he is very nasty.
And S6 is great because you can cast wish in the late game once you get a ring, a coin and a cap, which he can all forge if needed.
