There are so many options that leave the AI with almost no chance to win, I'd have to remove a good percentage of all spells, items, and sacred units just to make a dent. The speels you mention actually rate rather low, they are almost never key MP spells. I can tell you though, the AI does perform a bit better in CB than base game, since things like shades and light cavalry aren't just throwing gold/gems down the drain.
