Yep, it's all about the Shield spell.
The big-*** yeti can kill your keep in one shot if he manages to advance about 2/3 of the way towards your side of the map, but his attack animation takes a while and he stops whenever he does it. So spam small, fast units at him to keep him busy and locked in place while you build up mana and hard-hitting troops. Then, when you have around 300 mana, charge with everything you have and cast shield just before he strikes. When the shield runs out, recast, rinse and repeat.
He has a ton of HP but no special defenses, so chances are he'll go down before you run out of mana.
