You know who loves becoming a local of Rohan? Sam Gamgee, that's who.
Get him loaded up with Nor am I a Stranger, Herugrim or Golden Shield and he is an attacking or defending beast. Assuming you are playing a low threat deck, Sam gets double bonus from his readying effect with these cards (when he readies, his spirit AND attack/defense boost 1 each), giving him an attack/defense 6! Add Rosie Cotton and/or Celebrían's Stoneto the mix and make it an 8 or 10! With Hobbit Cloak and Staff of Lebethron he is virtually indestructible. With this combo you can also use Protector of Lórien to charge up his attack/ defense further by discarding. To top it all off, you can still use those spirit points to quest with AND cash them in during the fight.
Takes some set up, but when up and running Sam Gamgee really is a top draw Squire of Rohan!
