Ore
Treasure 4
Worth $1
Name a card type which hasn't been named this turn. Cards of the named type cost $1 less while this is in play.
Love the card. Compare with bridge and quarry. But it's pretty useless without +buy, so it might be better as a non-terminal, non-serial action? Note that you can name any type, so you could get multi-type cards down even more. Or maybe I can actually give this a buy? Can I? Is that not too strong? Issue is, first one's going to be just better than silver too much there I think.
Tough question here. Let's say Ore offers +Buy and compare with Bridge:
(1) Bridge consumes an action, making it harder to spam. Ore can be played in multiples much more easily.
(2) Bridge operates on all types; Ore on only one type per play.
(3) Bridge stacks, whereas Ore cannot stack (except with multi-type cards, but I think we can mostly regard that as insignificant for balancing/pricing considerations).
The first two points might seem to counterbalance each other, but I don't think so. Because how many times do you want to buy two cards of different types? Obviously it happens. But lots of times you only wind up using one of your Buys, and when you do buy more than one card, lots of times they're the same time (two Minions, for example; or a Province and a Duchy in the endgame). The ability to buy different types at a discount doesn't seem like enough compensation for the lost action. So Ore wins so far.
But now we come to point (3), which is that Bridge can be so game-dominatingly powerful when stacked. That's far and away anything Ore can do under ANY circumstances. Ore can be spammed more easily, yes, but when it is, the benefits only accumulate to a point.
So I think that, yes, you can add that +Buy to Ore and be quite balanced at $4. I think the "average" use of the card will be better than the "average" use of Bridge, but on the other hand Ore has a much weaker upside.
Soldiers' Village
Action 4
Discard 1 card
+2 Cards
+2 Actions
Quite possibly a bit too strong, as if you've got any bad cards of the other four, this is going to be really strong, like a level 2 city. On the other hand, it really might be quite fine.
It's tough to say, since that Level 2 City effect doesn't stack. Roughly speaking, you can only get that Level 2 City effect once per green card in your initial hand. The effect of the card is not a million miles removed from
ChaosRed's Village card, which struck me as seeming quite balanced. His lets you replace a green card you might have drawn; yours requires the bad card to be in your initial hand but allows it to be something besides a green card, like a Curse or Copper. Ultimately it's probably a wash. Thus, my suspicion is that it's probably balanced. I do like it.
Mercury
Treasure-Attack 4
Worth $2
Every other player with 5 or more cards in hand draws a card then discards 2 cards.
Could also switch the order if this is too weak, but I have a feeling that would be too strong. I actually think this is pretty likely good where it is.
To respond to goober's comments above, Mercury is a Treasure and therefore doesn't consume an action. Thus, the attack *should* be weaker than Militia's.
To respond to Elyv, the attack doesn't stack, so multiple plays can't hurt anybody worse than just one.
Here's my feeling on the attack: "Every player with more than 5 cards discards 1 card" is a frightfully weak attack, and this is even weaker. Think about Vault's "every other player" effect. That's there because sometimes other players want to do this. Mercury's attack is basically the same thing, only weaker still, because the players get to draw first. Of course, Vault's effect is optional, and that's a really big deal. Still.
But, WW, I've reconsidered since I emailed you about this card. Yes, the attack is weak, but then again it ought to be. It's effectively a $4 non-terminal. The attack really shouldn't be any stronger than Spy's, which draws a card instead of offering +$2. So I think my initial impulse here, that the attack is
too weak, was wrong.
However,
there is this. Not that this is a principle you have to adopt for your own cards. But I think on a board with Royal Seal and Stash, this is going to look like a bargain at $4. If it were me, I'd keep this card as written, but price it at $5 just based on Donald's remarks and experience here.
Really enjoying this thread, WW. Considering your cards are great thinking exercises.
