A deck based around Keeping Count (KC). Early game Boromir racks up kills to get some resources on KC, using his ability to ready (once per turn) when necessary. Ideally you want a copy of KC in your opening hand, or at least Master of the Forge. Master of the forge makes it quite easy to the important attachments, including another copy of KC. Bonus point if you can play a third copy of KC across the table!
Mablung can net a lot of resources, especially when you use his ability outside the engagement step with Westfold Outrider and Wait no Longer. Mablung is the main source of questing but he can also defend when Wingfoot triggers. Behind Strong Walls can ready him in a pinch.
Once Argalad gets a copy of KC, with a few + he can use his ability to the fullest, without putting resources on KC. Later on he really becomes a monster, and can easily one shot enemies as they enter the staging area with Hands Upon the Bow, or quest for a ton with Grappling Hook, both of which can be used after the staging step (or just use his regular ability these are not needed).
A bit low on the ally side but so far I have not found it a problem, there is a fair amount of action advantage. Threat can also be an issue.
