The most UNPOPULAR faction in Heroes 5.

Maybe it won't be necessary. Since gargoyles are immune to elements, and zombies are not, a hero with gargoyles can fly away with them and simultaneously attack the zombies with spells:D

I'm talking about their attack power, not about the various tricks that can be used. And imagine what to do if the hero doesn't have magic; the gargoyles will still lose. You can't fly away forever:D
