Which monster do you like the most in Heroes 5 at level 7?

I like almost all of them except for the Bone Dragon. It's too weak compared to other level 7 creatures, and its abilities aren't impressive.

Even though it's weak, it has a growth rate of 3, you can resurrect killed enemies, and its curse is quite powerful! The Necropolis's strength lies not in quality, but in quantity! Plus, the Banshee's scream... :(
