One of my friends said that we should combine a Lich and a Dragon and make a Lich a Dragon Rider (level 7). From a distance, the Lich shoots and can cast spells, while the Dragon fights up close. And the Dragon should be made as I suggested, so that it would be intimidating.

Dragons are everywhere))) there are already so many of them))
but I like it this way too) although I liked the Knights more in the 3rd game) and they didn't make Death (Death itself!) a unit <_< (why isn't there a unit called Life? or Birth? a big belly approaches enemies and gives birth)) haha, or explodes)) ... and Death looks like a hero <_<))
