This deck is designed to be used in conjunction with the decks "Spear shall be shaken, Shield shall be splintered!" and "A sword day, a red day, ere the sun rises!". The task of this deck is to kill enemies. Allies can be discarded for various effects, such as Riddermark Knight's charged up attack or using the Westfold Outrider to drag across enemies. These effects power Éomer's ability which, when boosted by Firefoot and Gúthwinë, leave him attacking for 9. Gúthwinë pulls even more weight as it allows allies to be returned from the discard pile to your hand. Recurring Westfold Outrider lets Éomer use his 9 every single turn. This can get even better with Heir of Mardil from the "A sword day, a red day, ere the sun rises!" deck, which should be placed on Éomer allowing him to be readied by Théodred and Horn of Gondor, but with Diligent Noble this combo can be set up on any hero.Erkenbrand, Déorwine, Warden of Helm's Deep, Feint and Sterner than Steel should all help to keep the defense as tight as possible.
After Boromir or a Steward of Gondor from the "A sword day, a red day, ere the sun rises!" deck hits the table, hopefully found quickly by Gather Information or Send for Aid if it hasn't been drawn yet, it would optionally engage any enemy that the other two decks couldn't easily handle, see unique boss enemies such as The Raven Chief or Thaurdir. Playing Oath of Eorl, you hit as many enemies as possible as hard as possible. Use Rohan Warhorse to help keep up the momentum, especially on a Sword-thained Legolas, who can use his ranged to snipe weaker enemies engaged with other players. Alternatively a Sword-thained Boromir would open him up to several steeds and Dúnedain Warnings, letting him act as a reliable counter-attacker, using his resources to give up a Warning so he just takes the one damage, readying him again.
The attachments in the deck work well to bolster the other decks in the Fellowship. Spear of the Mark is ideal for splashing around, especially with a well-timed Forth Eorlingas!, but are perfectly placed on Dúnhere. Golden Shield would work well on either Théoden or Éowyn, and the Dunedain signals can be splashed as needed. Háma's ability can be used to recur any event as needed, but a personal favorite would be Skyward Volley for repeat direct damage.
Could this deck be any better for its role in the Fellowship "Arise! Arise, riders of Théoden!"? Let me know what you think below.
