As people have allready pointed out, Cow is almost as Good as Grand Market, a card which costs with a very harsh buying restriction. If you changed it to only +, nothing actually stops you. It should be noted though that a card that just gives +1 Card, +1 Action, + is usually considered worth . People here refer to that as Peddler sometimes, allthough the actually existing card Peddler costs . A term that's less confusing probably is "cantrip money". Either way, there is no official card at that price point, so it's not like Cow with only one coin would be strictly better than an existing card. It will make some people feel it's too good, though.
Pig is interesting. It's cantrip trashing, but it reduces your hand size by two. Might still be rather good.
I don't really get what the goods do. Do they anything? Currently they don't seem to have any use. I mean, without any use for a card like Egg, Chicken is just a Necropolis and strictly worse than Native Village. I know you said Livestock cards should make a decent part of the kingdom, but you really shouldn't make cards that are only worthwile if other cards from the same expansion are there. Chicken is kind of the Scout of this set.
I would argue Sheep is incredibly hard to track. Again i don't really get the point with goods.
Noooo... Don't make a reaction on drawing a card, like Rooster. Your hand is a secret to people. Nobody can check whether a Rooster you play is the card you just drew. It's not in the rules. It's extremely easy to cheat here, and, dare i say, it's also weird mechanically. Not to mention with the current wording, Rooster arguably doesn't take up an action to play if you draw it (so you can use terminal draw to activate it), helps activate other Roosters and has an activateable effect that's better than a card. If Rooster said "You may play a Rooster from your hand. If you do: +1 Card", that would be an entirely different thing. But, thinking of it, also a different card.
Because of Mule, a note about edge cases: Whenever somebody in this forum makes a general claim, people will try to think of a way to make sure he's proven wrong. It doesn't matter how absurd or irrelevant the edge case is. For example, i might say the fact that Throne Room says "play an Action card from your hand twice" isn't different than "you may play an action card from your hand twice", because you wouldn't play it if you don't want to play the other card, people will jump out of bushes at all sides and say "Edge case: Conspirator!" or "Edge case: Golem!". Either way, edge cases shouldn't be considered when you think about whether a card that says "discard a card" is worse than one that doesn't. Unless of course, the card itself does something that profits from you discarding things.
So yeah, Mule is strictly worse than Market Square and probably too weak for . As , and are basically equally easy to aquire, it doesn't seem to be a card that would be bought at all.
Farmdog is kind of a mix between Spy and Lookout. I think it might be okay, even though cantrip trashing is strong. The fact you don't know what you'll hit nerfs this enough, i think.
Wolf is again a card that's useless without other cards from the set. Actually, you could even have a few livestocks and Wolf would still be dead.
Same for Shepperd...
...Pastureland...
...and Spices
Ranch is similar, but still has a use without Livestock cards. In that respect, it's a bit like Fortress.
Goods Merchant is a cantrip without cards that give goods. Meh. The fact that players can replace their starting Estates with those basically means everybody can at least open /. Pretty crazy.
Cheese Maker... again, doesn't work without Cow. I know, you said "use many of these in one game", and i see how that works. The problem is just, Dominion simply isn't the kind of game that does that on itself. The premise is that you can just play with random cards. So if you really, really want to make sure two cards are in one game, you have to make this part of the cards. Cheese Maker could simply say "Setup: Add an additional kingdom pile so that Cow is in the kingdom" and vice versa with Cow. Bonus: You can balance the cards easier this way. Probably it would need a rules clarification on what the sentence means - i implied that it adds Cow if it isn't allready there and another pile if it is.
Milk, Wool, Eggs, Cheese: Do these anything? You have listed their costs, but i'm not sure whether you actually mean costs or whether they produce an amount of , like Treasure cards? Even if Egg did produce , it would still just be a Copper, which is an awful thing to gain for a Chicken. Mind you, Chicken gives Actions and asks for a deck made of mostly action cards, while the card it can gain is awfully weak and clogs your deck. Or am i missing something obvious here?
Sorry if i'm being a little harsh. I think a lot of the concepts would work better if you forced the use of the piles the cards depend on. Like "Setup: Use an additional kingdom pile containing a livestock card", "...so that Cow is in the kingdom", etc. Also, i'm curious what the goods are about. Cheers.
Nope, not harsh at all. This is exactly what I wanted.
I'll address the goods cards first. The essential idea is that using live stock, you can gain these cards. Then using goods merchants, you can trade these in to get mountains of golds.
The idea with chicken is that it won't be completely dead, and is a cheap and easy card to throw onto your pasture for quick golds, since the majority of the pasture land cards take a while to get going. If Goods merchant can allow people to open 5/5, I'm not sure if that would be a bad thing considering it would a) change the game substantially, for better or for worse, and b) speed up the already slow goods cards. I get that this is unclear in the rules, and will try to explain this better.
When I have some time I'll fix the issues with Wolf, Pastureland, Spices, Shepherd and Cheese Maker.
I've changed Cow to a cantrip coin, so I think that fixes the problem for that one.
I really liked Rooster, but I now see your point. I'd love to find a way to get it to work without it being a trust system, but I guess I'll either have to scrap it or just use it with friends.
(Also, terminal draw to activate was the idea, it's supposed to fix the issue of having a smithy or some other power house draw card in an action stacking deck. The above still applies however.)
All in all, you've brought up some great points, so I'll try and fix up the set. Thanks for the help!
