While many people are discussing the power of Thengel, Deeping Defender and Morwen Steelsheen, I think that the ALeP card that really allowed Rohan to become a top tier archetipe with the Children of Eorl expansion is this one. In a pure Rohan lineup this card compresses card fetching and resource acceleration in one very convenient and efficient package. And in a Bond of Friendship Rohan deck it can become even better, though I would argue that it's better in a normal 3 heroes deck simply for the possibility to include 3 copies of it in the deck
10/10 would ride to war with the Rohirrim again.
