I like the basic mechanics and see a lot of potential to flesh out the gameplay loop and expand on the mechanics. It's very fun to engage with, despite the lack of balance.
I also noticed that Chalice of Life seems to be bugged---it appears as though its action isn't consuming its resource, allowing it to be used an indefinite number of times in a single day. If Chalice of Life is drawn early enough, exploiting this is a guaranteed win condition, as it produces exactly the resources needed by Sunken Reef to get victory points.
