The way to handle this is simple. 1 Lizard King set to cast fanaticism and 75 light infantry divided into three squads and set to fire at closest. If you can afford it add a sauromancer or two set to cast terror, and a couple shamans casting curse. If you are fighting the giants in your own dominion, you should be able route them easily. Swarms of predator lizards should also work, reasonable well, although you will take heavy losses. The key is a Lizard King casting fanaticism.
