I think it might be a little but the fact that anyone could just have a zombie army makes it a little fair.
And yes, I did think of this before the New LEGO castle line, hell, I've had it in my head for like 6 or so years now! The new amount of skeletons I can get just make it easier to make a grimlin army, currently 7 strong.
There, I've edited it so that the grimlins have the correct movement and and a cooler picture.
