So there's a lot of Caldara and Emery hate, but after making a bit of a "first draft" mono-spirit deck and trying it out on a few quests, I actually think Caldara is really fun.

Glorfindel and Eowyn are a bit redundant as questers, so given a friend's second deck, I would happily swap one for Eleanor for more support. The strategy is obvious; be able to replay Fortune or Fate as much as possible, and fill the discard pile with allies. Will of the West is to efficiently mix Fortune or Fate back in if it gets put on the bottom of my deck by the Map. Some games were overwhelmed with enemies, say for example in the seventh level. Giving Caldara a bonus 1 defense from Arwen, defending with maybe some damage, discard, get allies, replay, and there were even some times I managed this two turns in a row. It is extremely effective. Emery has fantastic stats for an ally you can play for free, and does a great job of putting more allies in the discard pile.
