The power of C'Tis lies in its powerful mages. Sauromancers are the most powerful death mages available, and Shaman are cheap enough to use as communion slaves to cast all the nature and astral spells you want.

Your normal troops are primarily designed to delay your opponents and give your mages enough time to do their work. Drain life is an excellent combat spell against living units, as you will never run out of fatigue while using it. Raise skeletons allows you to flood the battlefield with units to wear down the enemies. Your fire 1 sauromancers can cast banefire, which is an extremely powerful combat spell. You also have access to soul slay through the use of teams of four shaman acting as communion slaves with one master. This is the bane of powerful but expensive units with moderate magic resist.

If it's a fire 9/water 9 Jotunheim, then his economy is likely going to be quite poor. As long as you can defend against his armies, then you should be able to prevail in the long run.

I would also suggest summoning a few bane lords and equipping them with flying boots, jade armor, and wraith swords. Regen rings are nice, but not necessary. They probably won't be able to take on a Jotun army by themself, but will work very well in combination with your troops and mages. Just remember that each Jotun woodsman needs to kill at least five of your troops to win the economic war.
