Council of Elrond

Any idea of how to play Tower Raided on Barad Dur? Basically I need to change a into a

I can't think of any way, offhand. It's possible to turn Lorien into a through the use of hazards, but I guess improvement for Barad-dur is out of the question.

Lórien as a shadow hold? You start with the Balrog, of course, but what cones next?

Doors of Night
New Moon
Gloom
Choking Shadows
Awaken the Earth's Fire

Alternatively, you can use the Witch-King of Angmar for the last step.

I find it funny that it works using Choking Shadows that will block the sight of a new moon.
That is like Frodo with Narsil+Anduril or Halbarad with the One Ring.
