How the fuck am i suppose to win games?

I lost 26 games and counting. I really don't know what the point of this army is. The point is that this is a glass cannon army. Except i'm just glass and not cannon.

I can shoot a unit of 10 Lichguard with my entire army. It then lives reanimates everything and then i get tabled.

I always get tabled because i don't do enough damage. Even in casual settings.
