This deck is part of a two-deck Fellowship used to play Helm's Deep for the Cardboard of the Rings Quest of the Week.
The Fellowship description contains details of the quest playthrough and campaign mode information.
This quest recreates the epic siege of Helm's Deep, with an endless stream of Uruk-hai and Dunland enemies to deal with, alongside the unique Defense keyword where for once it is the encounter deck that is trying to progress the quest.
This point in the Campaign gives an opportunity to change heroes. Theme demanded an entirely new lineup for this quest, with Théoden, Éomer and Erkenbrand leading the charge for Rohan.
Théoden practically requires an ally based Rohan deck, which is what I built. However, Éomer and Erkenbrand are powerful combat heroes in their own right, with the remaining deck space largely reserved for their attachments. Éomer equipped with Gúthwinë is a particularly potent combo, able to defeat any enemy in the quest single-handed while supporting the wider ally strategy.
