PS: You could also pack a
Pippin, Hobbit of Some Intelligence in there, just in case you face off against non-swarm shadows, so you can start him and Boromir, and IF you can find room, maybe a Diendal. Then again, if you're playing Moria Swarm, and pack the cicling Elrond and lose the events (maybe some
PATHS, but that'd be it), you can probably get away with a slightly bigger deck, say 35 each.
