A straight forward Outlands deck with Denethor receiving the Steward ship as per the norm, with him passing resources to the other two. This will trigger Heir of Mardil, I would probably put it on Prince Imrahil, but that's just me.
The Armored Destrier goes on Denethor however, if the Prince gets Sentinel via Dúnedain Signal (side board), than he should get the mount.
A Very Good Tale should allow for more allies to come out quick for buffs and Imrahill can pull allies out of the deck if necessary.
I am planning on taking this to a Fellowship event, any feedback would be fantastic!
