Ambush at Erelas (two-handed)

tale of years

This was a tough one, even with this combination. The traps help mitigate a lot of the enemy engagements, and the Spirit deck engages the Ringleader. If Thengel doesn't have extra defense from the dunedain warning attachments, chump blockers are needed, which can be difficult if you've discarded most of them. Theoden+Herugrim + a buffed Idraen or Celador can do the full 5 damage per turn. Use Morwen to heal or lower threat as needed. Note that her ability triggers whenever a Rohan/Gondor ally leaves play, not just when discarded, so she can trigger off of chump blocks. Beravor does card draw if either player needs it.

You could definitely switch out Beravor and Idraen for more synergetic heroes. I have them in due to a custom campaign.
