So my wife I an played this again last night. She used her "Frodo, Loragorn, Glorfindel" deck and I created something fun, just for this scenario. The first game Mumak showed up early and everything just went downhill quickly. The second game we were able to stage 2 but the siege combined with the archery was just too much. I really feel like siege is the hardest quest type to deal with. A good number of heroes with decent willpower also have decent attack, which means you often don't have to change who is questing much between Battles and traditional quests, but with Siege you end up having to send your best defenders to have a chance of succeeding, but with enemies all hitting for 4 or 5, you need your defenders to keep from getting overrun.
In any case, on our third try we were able to keep Celador alive and just squeak past stage 3 before the staging area filled up. The onrush in stage 4 was quite epic, but we had enough allies still alive that we beat the quest the round after progressing to stage 4.
The Spirit/Lore deck is functionally similar to Frodo/Glorfindel (Spirit)/Aragorn (Lore) deck above, so I won't bother to list it. My Tactics deck was really effective as the blocker/quester in early stages, and the attacker to deal with all of the enemies in the critical 4th stage. The spirit cards and songs were splashed to allow for "Test of Will" because "Blocking Wargs" kept kicking our ass in the first quest stage. It still needs some tweaking, but it did a good job of dealing with the onslaught of massive enemies that this quest deals out.
(Starting Threat: 31)
Beregond: Defender extraordinairre - get a plate and spear on him and let him go to work
Hama: Primary attacker; use his ability to get a Feint, Foe-Hammer or whatever other event is needed back into your hand
Beorn: Primarly quester or attacker; depending on how many enemies are out. Can even block bats or Southron Company in stage 3 or 4 (if your threat is less than 37)
Vassal of the Wind Lord x3
Winged Defender x3
Defender of Rammas x3
Gondorian Spearman x3
Eagles of the Misty Mountains x3
Trollshaw Scout x3
Spear of the Citadel x3: The first one goes on Beregond (for free!) and others go on Spearmen or Defenders of Rammas
Horn of Gondor x2
Song of Travel x3
Citadel Plate x2: I just wanted to draw this more quickly so that I could get it on Beregond, 8 hit pionts might seem like overkill but between the tracheries and archery, he will still be taking damage in this quest.
Dwarven Axe x1: For Hama (when are they going to print a Spear of the Rohirrim already?!)
Feint x3: Well hello, Mumak, and *every* other enemy in this scenario
Foe-Hammer x3: Get the dwarven axe or a spear on Hamma and this card is huge
Hail of Stones x3: Essential for stage 3, especially to get rid of those damned archers
A Test of Will x3: Blocking Wargs!!! -- just no… I have another name for that card, one that I won't repeat here
Behind Strong Walls x1: Really good with Beregond or Defender of Rammas, since the Southron Companies usually attack at a 5
Galadrim's Greeting x1: Help avoid threat death in stage 4 (the other deck had threat lowering as well, so this was just supplemental)
Hasty Stroke x1
Thicket of Spears x1
Blade Mastery x1
