Walkthroughs for custom maps.

I beat Witch King 2; the battle wasn't difficult. I positioned the archers so that a few liches remained, so they wouldn't do much damage, then I killed the flying and ground units, resurrected my own, and killed the remaining liches. I freed Galadriel and received a Clone or Phantom, which is very useful when there are many Archangels :)

Another tip: Free Trebeard. Send him to fight in the first wave against Saruman. If he fails, finish Saruman yourself.
Translation: Free Trebeard, send him to fight in the first wave against Saruman. If he dies, Saruman will kill himself.
Question: Did I translate correctly?
