Your options for
Castamir are:
- Legolas shoots him 4 times
- Legolas shoots him 3 times then use Citadel
- Legolas shoots him twice then use Stone Tower
- Aragorn with Anduril and Last Alliance fights him twice, taking a wound each time, then Dervorin discards him or you move again and shoot him with Legolas
- Faramir with Last Alliance fights him twice (since he can't exert for Raider Halberd he won't overwhelm Faramir), then Dervorin discards him or you move again and shoot him with Legolas
- Frodo fights him and Boromir pumps Frodo, then Boromir dies in the fierce
- A gondor companion uses Noble Leaders to not be overwhelmed and then someone dies in the fierce
- Two companions die (if you don't have any other options, which is mostly likely at site 2 which is why you should be careful not to put too much in the pool if you can't deal with Castamir at site 2)
Realistically, even if
Castamir kills 2 guys once he is exhausted you can easily move again and then shoot him with Legolas since he will have no way to heal.
It's definitely not easy and you will get stopped by
Castamir sometimes, but you do have a variety of ways of dealing with him. Multiple Great Hill Trolls at sites 5-9 is actually much worse since they discard whatever conditions are key and then you have a hard time dealing with multiple big fierce guys.
Don't get me wrong, the man/elf deck isn't unbeatable by any stretch of the imagination, it's just really solid against a variety of things.
Dwarves just weren't popular after
Aggression got banned (which was between Reflections and Mt Doom) because
Honed wasn't nearly as good and you couldn't
BRC away the entire support area since you weren't more than damage +3. They got really good again once
Black Rider came out and you got Thrarin companion and
No Pauses No Spills to draw cards. I actually think Dwarves are still really good in movie block, but they aren't quite on the same level as Elves with
Galadriel LR, Man/Elf, or Knights.
