All I see is a complete massacre of my forces, you charge my eternal guard, they flee. You probably run them up, then you can finish of my glade guard.
A good round of shooting from a lot of Gutter runners on my treeman, and his luck will run out sooner or later. And if he does do something, he will stomp the Nightrunners down into the forest. But you will have complete magical superiority, so you can do what you want.
I will probably get the tower from you and that is about that.
