Thanks for playing and taking the time to write up your thoughts! I hear you about the synergies, thats something we want to work on in the next couple weeks as we update the game. I think you're right about werewolves being too specific.
Vampires have another function that's not well highlighted right now in the game. Because they have the #blood tag, rivers will become blood rivers when next to them, which is very useful! We're trying to make the tag system in general more clear, but hopefully this tip helps in the meantime :)
About the deck building feeling random, I'm curious how often you're using the reroll feature? That is something we added so it hopefully would feel a little less random but I'm not sure how many players find or use it.
Anyway, thanks again for playing and I hope you like the next update!
