So, I was playing Dark Ages with Robz and Axe Knight over the weekend, and we tested out a few of the kingdoms. We did a lot with Knights. I sort of monopolized them, but because I was focusing on those, and Robz was just buying Silver and Gold, he still managed to pull a win, despite my incessant trashing.
Also, Graverobbing Pillages is a lot of fun, especially when you never actually bought a Pillage. Also a good way to recover your Knights when they trash each other.
Cultist is a beast. It can work so fast because of the chaining, and Ruins just slow your deck down to absolutely nothing.
