I played with him before 3 days. and about the mistakes: 1- the first shade i controlled,it had a immortality but i press by mistake the ancient excusioner. 2- the angel died when i was going to control the elves. so i had no elves and no markets and he took the elves easily and his assassins became powerful. but i know that serg is not easy to lose like that.. maybe I was luky in the game.
