If Citycrusher becomes a commonly played card, I'll think how to deal with it. But for now, I think Monarch Cloak is the bigger threat. For just 3 cost, it will silence your relic, both making it useless and making you unable to replay it with void effects. I don't think Citycrusher will be that popular, but I will certainly adjust the deck in the near future to deal with Monarch Cloak.
Probably Hail and some 2 discard cards you like the least? You could put other situational cards, card draw like Hard Lesson or alternative payoffs like Quicksilver Mirror into it. I chose not to have it because reduces the consistency of our combo. Unlike Throne, Expedition only has 4 market access cards, so you cannot use the market for the combo pieces.
