This should be such a cinematic card but it's just hard to find to right use-case. When is it ever really a good time to play this?! The COMBAT phase restriction makes it a bit awkward. I guess the point of this is to avoid some big enemies or nasty engagement effects - if you have low enough threat - and then snipe them. The problem is that you need enough high attack heroes (Spear of the Mark helps). But generally you really only have 1 or maybe 2 dedicated attacking heroes. Of course, this could also be a way to get Éowyn to go berserk and clean up the staging.

Essentially this should be Hands Upon the Bow for Rohan's cavalry, but that card at least helps with a +1, can be a character, costs only 1 resource, and most importantly can be played in ANY ACTION WINDOW (and therefore helps you quest).

Forth Eorlingas! should be a charge cry for all Rohan characters, not just heroes. That could be a fun way to gamble on holding back your questing characters, forfeiting progress on the quest, and doing a good clean-up round of staging.
