You're not very good at math, buddy. There will be 5 Titans, and even then, one will have incomplete health. 85. Most likely, they will create 6 Titans, but what's the point of creating illusions? And what about the fact that a Wizard can dispel them? He has a higher turn priority than the Titans.
It would be better to take out the Mage with a Djinn first, and then create illusions. But even here, there's a BUT: the Chaos Dragons keep flying.
Illusions, in my opinion, are not a viable option.
