Putting your SC in the right place to do the right things is part of the strategy, so don't use them to defend a province if your PD is going to cause him to rout before he's done his thing.

What you could do is try casting beserk, as I think beserk units carry on fighting even when the army routs. If your SC then beats the enemy, I don't know whether the winner is the player who routs last or has the last man standing, but your opponent will barely have an army left.
