Nice! Moria Archery is a great shadow and a lot of fun to play!
Moria Axe is actually quite useful in a Moria Archer deck. If possible, give it to the
Moria Archer Troop to deal +1 damage and pump his strength, put the Troop on Swarms and then recycle the Axe with Relics. Ideally, the
Moria Archer Troop can exert twice raising it's strength to 14. And with just one
Armory out the axe is free!
Other surprise cards in a Moria Archer Deck is either
Denizens Enraged or
Drums in the Deep. No one expects pumps in a Moria deck and if you can get your minions through the archery phase a surprise pump is often the difference between a dead goblin and and a goblin on Swarms.
I would ditch the Balrog and maybe a couple of Goblin Runners for 2
Moria Axe and 1 Enquea. You can easily go to 36-38 cards with a good cycling FP side. Dwarves combined with
Gandalf the Grey Pilgrim is perfect.
The aim of a Moria Archer deck is obviously to deal a lot of damage in the archery phase. That's the reason I think
Ancient Chieftain doesn't fit.
Guard Commander can pump your archers for Swarms but since he is on the table the Free People player can do some smart assigning and neutralize his ability (that's why I prefer a pump in hand).
Just som thoughts.
