I think I love everything.
I really really have to try out card based miniature games sometime, they appeal to me so much!
I find very clever how your miniatures don't really die, instead emptying your deck. The milling dual purpose mechanic seems to work nicely.
It's also very elegant how you don't have stats at all, just actions triggered by the cards which in turn are used for everything.
One thing that I feel is broken: Pupeteer+Desecration
I have to ask, since I haven't played it and don't know it at all. How much of this stuff is from Malifaux? Iirc Malifaux still has the typical "2 actions per miniature per turn, moving etc" and only showing cards from the deck whenever you made an action, sometimes having to make sums and compare between two cards etc etc. This game seems much much faster to play
Did you think about making the assigned cards have a specific suit or color? I'm wondering the pros and cons.
