My Trixy Elves against a large force of Fighting Uruk Hai and Warg Riders.  With Galadriel, Protectress of Lothlorien weakening the Courage of all Evil models around, my Sentinels fighting along Thranduil had little problem dictating the flow of battle.  And when they brought the White Hand to the breaking point, her Terrifying Aura caused the enemy to scatter quickly.
