One way to win is keep the other team stunned and disable there passive abilities. I see you dont have several key toons that would make it easier.
The team i used was DDE, Horus and prisoner. Another team was IE, assassin demon spawn an another ally.
You need to upgrade and evolve some talisman to increase your stats, that would be a great benefit. You dont need relics to beat night city, but they make it a lot easier.
