Okay... I already explained that the whole point is that you don't have to immediately attack two hundred units! You're just defending against two stacks of griffons.
-I personally start as a Vampire in the first cell next to the griffin, so it frees up a space for me, and then I move into the corner and attack it.
-And then you have some magic and a little bit of meat! Or, better yet, just create a map and try it yourself, and you won't have to prove anything to anyone.
