Solid game!
It was quite (coincidentally) thematic with the humans stepping back in terror the 1st couple rounds, before catching their resolve and chasing the undead abominations across the field.
Unfortunate for your opponent to have such limited list building options, but impressive he managed to take knowledgeable on a liche king. As you noted, they dont need it, but more importantly, its not even a listed option to take!
Morgoth just face tanking that hex was probably the most surprising bit.
You definitely seemed to favor stalling the mid and weighting the flanks. Which can seem to get you in trouble if a flank stalls and cant meet up with your mid board units in time. The general definitely pulled his weight with being a little bit of everywhere you needed him.
