In the right fellowship it can be quite the good card, being a 2/2 sentinel defender at 2 cost (or even 1 if you have SpTheoden) can be quite good. Also that 1 Willpower can be quite welcome in a Tactics deck
Ally. Cost: 3. 1 1 2 2
If there is at least 1 Rohan hero in play, lower the cost to play Guthlaf by 1.
If there is at least 1 Gondor hero in play, Guthlaf gains sentinel.
