Here are the first two cost 3 cards. I have modified the original post to include them there as well...
ExcursionThis is really meant to combo off of other cards in the set, or provide a unique way to recycle the cool victory cards like Harem or Nobles. It works off the discard pile, so you need a victory card in your discard pile to gain it to your hand. It's card neutral (you gain a card back for playing it) and it does not terminate, but of course, its usage is limited and on most boards, I don't see this as a compelling buy. However, with other cards on the board, it becomes extremely powerful.
Too narrow? Perhaps, but I thought it was interesting enough to see if it provoked any discussion.
VillaThis is my one "village" card (every expansion seems to have one). It is a pretty weak village, until you can ensure your deck will likely draw a victory card (or can fish a victory card with a card like Excursion or Scout). At that point, the card is VERY strong (perhaps too strong). I am very tempted to make the reward for having a victory card in your hand just get you +1 card. This way you get to a normal village (+2 actions, +1 card) but with an additional +1$, but you have to have a victory card, otherwise you get no cards (but do get +2 actions).
I do want a village type card, and thought this one might be fun.
There are two cost of 3 cards in the set, but I'll see if there is any harsh criticism or praise for these two cards, before unveiling them. And thank you all again for your great feedback!
