I know it's late, but now I have some time, so let's go ! (one of those cards is mine, and I already voted)
I didn't vote for all the cards I said good over, though, I'm sorry !
Relic
Types: Treasure
Cost: $6
Worth $2. When you play this, you may trash up to 2 cards from your hand and play area. If you trashed at least one Action card, +$2 and +1 VP.
Terrible at beginning. I find the "Action for VP" boring, because it's only one VP at a time. "trashing for money" is still interesting though.
Artist
Types: Action
Cost: $6
+$3. You may trash this. If you do, the first time you buy a Victory card this turn, +3 VP.
While this is in play, when you buy a Victory card, +1 VP.
Okay, VPing while greening, or bursting ! Just classical ! Could be nice, "rising the value of victory cards by 1", but only in close games !
Usurer
Types: Action
Cost: $6
+1 Card. +1 Action. Reveal cards from your deck until you reveal a Treasure. Discard the rest. Trash the Treasure; gain a Treasure costing up to $3 more than it, putting it on top of your deck. Each other player may gain a Copper, putting it into his hand.
Money money money !!! It leaves you with money on deck, it's a cantrip miner... I find it belongs to Prosperity, but swingy. Okay, Loan from prosperity is also swingy, too.
Treasure Chest
Types: Treasure
Cost: $4
Worth $1. When you play this, discard the top card of your deck. If it is a Treasure, gain a Silver
Too swingy and too poor to be interesting
Strong Room
Types: Action
Cost: $5
+4 Cards. +1 Action. You may return up to 4 VP tokens. Discard 4 cards, minus 1 card per VP token returned.
In games using this, at the beginning of each turn of the player who went first, each player gets +1 VP.
I personally love this mechanical ! But it kinda warps the game !
Metropolis
Types: Action
Cost: $7
+1 Card. +2 Actions. Treasure cards other than Copper produce an extra $1 this turn.
Hmm... with at least 2 treasures other than copper in action phase, it's a better Bazar, and it's at least a village ! Seems nice ! Though I don't like the name because it reminds me of the last "evolution" of City (village evolves into city, which evolves into metropolis, just like Pokemons ^^)
Stock Exchange
Types: Treasure
Cost: $7
Worth $2.
While this is in play, when you buy a Victory card, you may buy any number of VP tokens for $1 per token
I produce $40 due to my KC-(insert good drawer here)-Bridge engine !!! So I'll buy an estate and 40 VPs ! LOL !
Bad : Changes too much the aim of Dominion ! To me, VP tokens shouldn't be a goal for themselves !
Good : If you have extra $ to spend over a Victory card, or if you are afraid of buying that Colony/Province, just take a Duchy instead !
Chalice
Types: Treasure
Cost: $4
Worth $3.
While this is in play, when you buy a Treasure card gain 2 Coppers, when you buy a Victory card gain a Curse.
Uninteresting Quarry-like, only it boosts Gardens...
Surveyor
Types: Action
Cost: $5
+1 Card. +1 Action. +$1. You may discard a Province or Colony. If you do, +1 VP. You may return 3 VP to the supply. If you do, gain a Province.
Infinite VPS !!!! No, sorry, I already lost a challenge because of this idea !
Gilded Statue
Types: Treasure
Cost: $7
Worth $2. When you play this, you may discard a Treasure. If you do, gain a Gold.
When you gain this, gain an Action card costing up to $4.
So you have $3 minus $1, minus another $1 (because you will typically discard copper) for a gold ? Interesting, but not as much as Hoard, which costs less.
Railway Town
Types: Action
Cost: $6
+1 Card. +2 Actions. +$1. If you have played railway town at least twice this turn, +1 Buy. If you have played it at least three times this turn, +1 VP. If you have played it at least four times this turn, +$1. If you have played it at least five times this turn, +1 Card.
Sorry but I hate the idea of "If you played at least n / n+1 / n+2 ... times this turn". Only the first time (Crossroads + Fool's Gold) is enough.
Charity (A)
Types: Treasure
Cost: $7
Worth $4. +1 Buy.
While this is in play, when you buy a card, each other player gains a card costing at most $2 less than it.
Could be a nice attack.
A bit strange, maybe overpriced at $7 and with the +buy, but I like it.
Wedding
Types: Action
Cost: $7
+1 Action. Reveal cards from the top you your deck until you reveal an Action card, a Treasure card and a Victory card. If you do reveal a card of each of these types, put an Action card, a Treasure card and a Victory card from among the revealed cards into you hand. Discard the other revealed cards.
I don't like this mechanical of "until an Action, Treasure, Victory and then choose one Action, Treasure, Victory", neither do I like the one of Smelter below.
Quote
Palace
Types: Action
Cost: $4
+1 Buy. +$1.
While this is in play, during the Buy phase, Colonies cost $2 less, but not less than $0. While this is in play, when you buy a Platinum, +2 VP.
Setup: Add Colony and Platinum to the Supply.
I dislike the idea of being forced to play with Platinum and Colony, and I find it not interesting enough : what if in late game you miss $9 with this ? You have at least province ! Yes, but you can't buy Platinum too ! And it's not interesting enough to me.
Crown (A)
Types: Treasure
Cost: $8*
Worth $1. When you play this, gain 2 Treasure cards.
During your turn, this costs $1 less per 2 VP chips you have.
When you gain this, +2 VP.
I play crown, I gain two other crowns, which make me win the crown split and then the platinum split... another game-warper, which I don't like !
Cathedral
Types: Action
Cost: $7
Gain two action cards costing less than this and a Gold.
Kinda simple ! I like this !
King's Greed
Types: Action
Cost: $10
Put your deck into your discard pile. Look through your discard pile and set aside up to 3 Action cards from it. Play them in any order.
No, sorry, I don't feel ready to pay $10 for an action.
Mediator
Types: Action – Reaction
Cost: $3
+$3. Reveal 3 cards from your hand. The player to your left selects one of them. Discard it or put it on top of your deck.
When another player plays an Attack, you may set this aside from your hand. If you do, +1 Card, +1 VP, and at the start of your next turn, discard this.
Too complicated. But risky, and I love it. But it doesn't belong to Prosperity to me.
Prospector
Types: Action
Cost: $4
+1 Buy. Reveal the top 4 cards of your deck. Put the revealed Treasure cards into your hand. Discard the rest. Each other player may discard a Treasure. If he does, he draws a card.
Even less interesting than Scout !!!
In fact, it's like a "Smithy you play dead with a +buy" but you have to hope you're full of treasures ! And it's swingy too... so it's gonna be without me !
Jeweller
Types: Action
Cost: $6
+2 VP. Gain a Gold.
...no !
Hunter
Types: Action
Cost: $6
Trash any number of cards from your hand. For each card you trash, +1 Card and +$1.
Weak if you trash one card at a time, and good luck to trash several at a time. Because yougget them only once you reach $6...
Forum
Types: Action
Cost: $5
Draw until you have 6 cards in hand.
While this is in play, when you play a Silver, you may trash that Silver. If you do, +1 VP.
I prefer watchtower !
Statue
Types: Action
Cost: $7
Discard up to 3 cards from your hand. +1 VP per card discarded.
Infinite VP powaaa ! See above !
Aqueduct (A)
Types: Action
Cost: $7
+2 Buys. +$2. Reveal the top 4 cards of your deck. Put the revealed Treasure cards into your hand and discard the rest.
Hunter is baaaack !
Deed
Types: Treasure – Reaction
Cost: $5
Worth $2
When you gain a Victory card, you may discard this from your hand. If you do, +2 VP.
Nice enough...
Philanthropist
Types: Action
Cost: $4
+3 VP. Each other player gains a card costing up to $5.
3 VP for $4 is too much, even with the counterpart ! It makes the game uninteresing !
Clearing House
Types: Action
Cost: $6
+2 Cards. +1 Action. You may trash any number of Treasure cards from your hand. +1 Card per card trashed in this way.
I wanted a "laboratory+" for $6. I think this one is good enough, but I wonder if it can give a serious lead to the 1st player to reach $6.
Workhouse
Types: Action
Cost: $7
+$4.
...no !
Gemstone
Types: Treasure
Cost: $4
Worth $1. Rarity cards cost $6 less this turn, but not less than $0.
Setup: Add an extra Kingdom card pile costing $5 or more to the Supply. Cards from that pile are Rarity cards and cost $5 more.
I don't like adding piles to the Kingdom ! And what if the pile added isn't interesting ?
Ascetic
Types: Action
Cost: $2
Trash this and any number of Treasures from your hand. +1 VP for each Treasure trashed this way.
I dislike the idea of "Trash this and any number of cards from hand", sorry ! And neither $2 nor one-shots belong to Prosperity to me !
Dividends
Types: Treasure
Cost: $6
Worth $1. When you play this, gain a Treasure card costing less than this, putting it into your hand.
Either there are good treasures at $5 (Counterfeit/Good venture), or this is a good remplacing-card for Swindler, just like Farmland !
Villa
Types: Action
Cost: $5
+1 Action. Play up to 2 Treasures from your hand. Draw until you have 4 cards in hand.
I prefer "set aside and then play" and I hate the idea of "non-terminal cards that draw until you have X", and I already hated it before I nearly won a challenge in the previous contest
Golden Touch
Types: Action
Cost: $5
Trash the top card of your deck. Gain a Gold, putting it on top of your deck.
Midas disapproves the swingyness of this card.
Aqueduct (B)
Types: Action
Cost: $5
+1 Action. +$2. Discard a card. If you do, +1 Card.
While this is in play, Attack cards you play have no effect on other players.
I like this "stronger Oasis". I don't know whether the penalty is good, though.
Inheritance
Types: Action
Cost: $5
+1 Buy.
While this is in play, Treasure cards costs $3 less, but not less than $0.
An even worse quarry, which is too expensive to be fair, to me.
Crown (B)
Types: Treasure
Cost: $7
Worth $4.
When you gain this, each other player gets +2 VP.
Hmmm.... boring !
Standard Bearer
Types: Action
Cost: $7
Trash this card. Put your deck (not including your discard pile) into your hand.
*tries not to laugh* No !
Griffin
Types: Treasure
Cost: $5
When you play this, reveal your hand. This is worth $1 per Victory card revealed.
Once per turn, while this is in play, when you buy a Victory card, +1 Buy and +$1.
A VP-gainer, classical and could be infinite ! I dislike this !
Charity (B)
Types: Treasure
Cost: $5
Worth $1. When you play this, choose one: Each player gains a Copper; or each player gains a Silver. Either way, put the card you gained into your hand.
Is it an attack ?
I would prefer "only a silver for yourself only", that could be interesting but I don't know why I already thought to it but didn't post it.
Fountain
Types: Treasure
Cost: $6
Worth $0. When you play this, if you have no other Treasures in play, +2 VP. You may trash this immediately. If you do, +$2.
A treasure that encourages you to flee from other treasures ? No, sorry ! Not in Prosperity (and maybe not elsewhere too)
Savant
Types: Action
Cost: $6
+3 Cards. +1 Action. Each other player draws a card, then reveals and discards one or more cards. He gets +1 VP per Action or Treasure card he discards.
I hate the idea of "each other player draws and discards" without it being an attack, but it's risky. Is it gonna win ? I don't know, but it's not "conventionnal" enough so I didn't vote it (like other cards above)
Patent
Types: Treasure
Cost: $5
Worth $2.
While this is in play, when you buy a card that is not a Victory card, you may gain a copy of it, putting it on top of your deck. If you do, trash this.
Two platinums, two grand markets, two KCs... if good cards over $5, okay. But otherwise ?
Queen's Palace
Types: Treasure
Cost: $7
You may choose a Treasure card in your hand. Play it three times.
Girl powaaa !!! Can be very boring with Platinum !
Hedge Fund
Types: Action
Cost: $5
+1 Action.
You may return a VP token. If you do, +3 Cards, +1 Buy, and each other player gets +1 VP.
Setup: Each player gets +2 VP.
Hmmm... unlike Strong room, you are forced to use VPs to make it interesting ! I dislike this. It would change the game into a "VP ping-pong" and you would be poor if no VPs.
Mafia
Types: Action – Attack
Cost: $7
Each other player reveals the top 3 cards of his deck, trashes a revealed Treasure that you choose, and discards the rest. You may gain any or all of the trashed cards. +1 VP per card you gain this way.
Thief++ just like Expand and KC are Remodel++ and TR++, with one VP.
I hate Thief, so i hate thies... sorry, this !
Witch's Trove
Types: Treasure
Cost: $6
Worth $2. When you play this, reveal you hand and discard all revealed Curses. +$3 for each Curse discarded. You may gain a Curse.
You are not allowed to gain a challenge if you submit a cards which allows you to gain a curse !
Palladium
Types: Treasure
Cost: $7
Worth $4. +1 Buy. When you play this, trash all Treasures you have in play. +1 VP for each card trashed.
Treasure Kamikaze ! I dislike this !
Banknote
Types: Treasure
Cost: $6
Worth $2. +1 Buy. If you have 4 or more differently named Treasures in play, +$2.
Why not Cornucopia ?
Reputation
Types: Treasure
Cost: $10*
Worth $4.
Unless in play, this costs $2 less per card costing $6 or more you have in play, but not less than $0.
I dislike the idea of "cards costing $6 or more in play". And what does "unless in play" mean ? It means "either in your hand, in the supply or in an opponent's deck" ?
Silk Merchant
Types: Action
Cost: $5
+$2. You may trash two cards from your hand. If you do, +1 VP per token on the Trade Route mat.
Setup: Put a token on each Victory card Supply pile. When a card is gained from that pile, move the token to the Trade Route mat.
Clarification: The Trade Route mat and tokens referred to by Silk Merchant are the same as those referred to by Trade Route. If both Trade Route and Silk Merchant are in the kingdom and/or Black Market deck, use only one token on each victory card pile.
First time a card in a challenge refer to an existing mat, right ?
Too bad you have to trash your cards late enough to get benefit of this !
Indulgence
Types: Treasure
Cost: $5
Worth $2. +1 Buy. When you play this, the player to your left names a card in the Supply costing between $3 and $6. If you buy that card this turn, +2VP.
Original VP gainer. I like this, but will you buy that coppersmith for 2 VPs, or that Moneylender or Trading post if you already have several of them in your deck ?
Smelter
Types: Action
Cost: $6
Reveal cards from your deck until you reveal an Action card, a Treasure card, and a Victory card. Trash an Action card, a Treasure card, and a Victory card from the revealed cards. If you do, gain 3 Golds.
Not to me ! See above !
Rosary
Types: Treasure – Attack
Cost: $5
Worth $2. When you play this, each other player may trash a Treasure or Action card from his hand. If he does not, he gains 2 Coppers, putting one into his hand.
Interaction too weird !
...
okay, next time I'll talk about the cards first and submit then !
It took me 45 minutes... it's looong ! I understand why I was lazy to do so in the first contest !
