It's great to see that you keep working on your set and came up with tweaks and new ideas. Alas, I couldn't contribute as much as I wanted to because I have little time. Any every time I look into this thread and something comes to my mind, there have been tons of new posts I need to read to keep track of the discussion. Hopefully I can add something productive:
I like your aesthetic improvements. The new cards look nice and shiny!
Auction: At first glance a few months ago, I said I liked Auction. It's interesting enough to be worth trying. But I can hardly think of any case where it's worth buying, especially multiple copies of it. It doesn't fit in engines because you want to play all the actions and trash the other cards. It doesn't help Big Money more than Silver because with a high treasure density in your deck, especially with Golds, you don't want to discard them all to a "Secret Chamber that can't be drawn dead". Secret Chamber is a bad card. But Auction benefits very little from being a treasure because having multiples in one hand doesn’t help you at all. I would be sad if Auction was the only source of +Buy in a kingdom. It might be okay in a slog-ish game with decent drawing potential and viable Alt-VP. Auction can be a little better than Silver when you open with it, provided you draw it with Estates, but IMO it is outclassed by many $3-cost cards and possibly even by Silver. It might be acceptable at $2.
Convoy: I like Convoy or Guide either way. Stick to what you like best. I prefer the rephrasing “You may pay a Trade token to do X” but would also advice to scratch the comma. This isn’t Magic The Gathering where every punctuation mark matters. Here it just looks misplaced.
Gambler and Vendor: I can definitely see Fragasnap‘s point in that Gambler and Vendor perform similar actions when trashed but I comply with the popular opinion that Gambler is the more interesting card although it mostly provides non-decisions and can be frustrating. Opening double Gambler seems pretty strong; If you directly draw your other Gambler with the +1 Card, you end up with 5 cards in hand and trashed 2 from your deck. Even if you reveal your other Gambler and put it into your hand, you end up with 6 cards in hand and trashed 1 from your deck. It seems a touch too powerful for a $3-cost card, so you should at least test it at $4.
Vendor isn’t bad or anything… it’s not even that similar to Gambler due to the significant cost gap and the fact that Vendor wants treasures in your deck. But it’s similar to Stables, as you mentioned, and not very exciting overall. If you want to scratch one of these two, I suggest go with Vendor.
Refurbish: It’s off-theme and that might be reason enough to replace it. But it’s totally an interesting concept that could hopefully be implemented somewhere else, if not in this set.
Committee: I always loved Committee because it’s so innovative. Yet, similarly to Gambler, most times you play it, it’s a non-decision which card to choose and what to do with the chosen card. It’s those few other times where the decision is non-trivial that makes the card really interesting! Also it seems adequately priced.
Dignitary: This is another card I always liked. It seems pretty useful and innovative. Yes, technically it needs the line “Put the rest back in any order” but you can assume some common sense in players, at least when making a fan expansion. I’m working on a set myself and sometimes feel the need to add more text just to exclude unwanted wonkiness in some edge cases. But it’s a fine line between making things clear and presuming that all players are morons. For the sake of brevity of card texts (which I know you like), just stick with the version on page 28.
Barrister: By now, I made friends with the new version (I liked the old one, too). I just wish that Domains were associated with at least one other card additionally because I think they’re cool
I have a question (now I hope that I don’t seem like a moron): Do you put the treasure from the trash into your hand, too, or just in case you choose the Silver?
Barter: With the 2 Trade Tokens gained on-buy unconditionally, it seems really pretty strong to me. Even with no other sources of TT around, gaining and playing a powerful action card in the same turn can be a big boost. But I’m not sure if gaining 1 TT (or 1 TT per Silver you have in play) when you buy it are optimal. This should be tested carefully.
Conclave: I liked the old name more but, as I said, do whatever you like best. The change in wording is very elegant, in my opinion! Seems a good card to me.
General: You decided to change the wording a little so that forgetting to top-deck the card isn’t considered cheating. This a tough case to me because on one side, you want to avoid situations like that. On the other side, this makes General a little more powerful if we assume that good players deliberately choose the better option. The old version of General forced you to seed your next hand with the one-shot you played twice this turn, enticing you to play it again and ultimately losing it then (if you don’t have another General). The new version makes it easier to keep your one-shots. But maybe this is the boost General needed to become sufficiently better than Throne Room in order to justify the significant jump from $4 to $5. In general, General a good card and a clever addition to the set =)
Conscripts: There’s so much discussion going on about Conscripts and Barracks and Recruiter that I can hardly follow which are the current tendencies for each of these cards to become. The old Conscripts that just gave out Curses were definitely too strong with Recruiter, with Barracks I’m not sure. Now they seem adequate with Barracks but perhaps a little weak with Recruiter. Again I’m not sure here. They should be tested thoroughly. I feel that theorizing about it won’t help to assess how the cards ultimately play out.
I print my cards directly from GIMP, which is the image editing program I use to create the card images. I have step-by-step instructions for using that, if you're interested. IN FACT, if you have GIMP I can just give you .xcf documents to print and you won't even need the step-by-step instructions.
I would very much like the step-by-step instructions and the .xcf documents
Could you upload them somewhere?
