BryGuy with Silver Thief/Gold Thief
Clever to trash Silvers/Golds from the Supply to fuel its next play. This card is alright, but Thief cards have been tried many times before. For experienced players, these just add stop cards to your deck and remove stop cards from your opponent, helping them in some cases. Very good for newer players, though. This is about as good as a Thief card as can be made.
Builder_Roberts with Retired Militia
This is quite strong, but suffers from the Sea Hag problem: You don't get anything when you play this (Except when you trash.) Meaning that you want to trash this often to get the effect, which feels bad. The Villagers are a nice consolation, though. Buying lots of these lets you trash a lot of them, which let you play more of them, but the Attack doesn't stack, so you don't want to do that. In a way, this interferes with itself, so you don't want too many of these at the same time in most cases.
AJL828 with Broomstick
One of my favorite cards of the submissions. The discard might make it slightly too weak, but the 13 coin trigger is really unique!
sumrex with The Legend of Night and Day
Should have "from their hand" in the text, in case people play these with Golem or something. A decent card, but a bit convoluted. I understand it, but newer players might not get it.
4est with School of Witchcraft
This one is interesting and hard to judge. You want these for the points, but then again you don't want them because it leads to more Curses. Overall a good card, but I would need to playtest it to know how it plays in reality. It's also begging to have other Attack cards in the Kingdom, but sometimes duds on that. I see that it plays fine without other Attacks, but seriously, you really want those Attacks.
JW with Malevolent Witch
I like this card. Well-balanced. Not much to say about it.
Augie279 with Picket
Seems well-balanced and has some clever self-interaction. I can't find any fault, but there are so many cards and I have to choose only a few winners.
X-tra with Brats
Creative to use a Copper as a penalty card. May be a bit strong compared to Cutpurse, but gaining the Copper to hand option alleviates that. It forces an interesting choice like Torturer does. I like this card as well.
NoMoreFun with Usurper
This attack is brutal. It also might need an FAQ because of the order of discarding thing. This might be balanced, but I sure wouldn't want to play a game with this in the Kingdom.
majiponi with Soldiers Village/Armed Smithy
Soldiers Village isn't really an Attack, but I'll let that slide because it's easily fixable by using some other type. This pair of cards have several clever things going on. I like the pair, but don't love it. No suggestions for improvement, though. I think this is as clever and creative as it needs to be, I just happen to like other cards more.
n_sanity with Burglar
This suffers from the Sea Hag problem in that it doesn't do anything for you, it just hurts your opponents. Seems balanced for 7, but doesn't seem fun.
czzzz with Tree Giant
One of my favorite submissions. Very good card and the theme is well-integrated. My only complaint could be that it might be slow to resolve with multiple opponents, especially if you play multiples.
arowdok with Eternal Struggle
I'm not sure on the balance of the card, but I prefer elegant cards. This one has quite the wall of text. It has 10 lines of text, which is more than Possession has at 8 last time I checked. The replaying every turn is clever, though. I'd like to see a simpler version of this card in the future.
Xen3k with Goblin Village
Lots of hedging/nerfing on this card to make it weak enough for 2. It's a good card, but a bit plain. I'm surprised you were able to fit so many effects in such a small number of words. It does a lot, but a lot of it has been done before. The new thing, that it's a Village/Attack, I've tried before and I could never get it to work correctly. Maybe this one finally does it right.
Erick648 with Almoner
One of my favorite cards of the submissions. My discard pile is seemingly always empty; This puts a Copper into the discard pile for me to grab every time. It limits Copper gains to 3 so that it isn't a rehash of Counting House.
SignError with Faun
Very good card and made in the style of my favorite mechanism: choices. I can see players playing Faun to gain Fauns early and then trash them later to give Curses. Good synergy, well-balanced.
nagdon with Battle Witch
Elegant and simple. I really like this card. The only downside is that it doesn't do anything new. Not much else to say here.
emtzalex with Dragon
This card is really powerful. I'm sure it's fine when people gain it mid-game, but people are going to be rushing for these. Getting one allows you to quickly get more of them in many cases, shutting a player out if that happens. Cursed Gold and Desperation both make this card an instant win for the lucky player, though.
Ltaco with Rebuke
A bit strong. You can buy unique cards early and ensure that this hits frequently. That can be mitigated, of course, but I still feel that this is too strong for a 2-cost.
J410 with Vizier
Simple and elegant, but I don't like that idea of a -1 Action token. Wow, that really hurts. Even with the nerf this is scary to me. I'm glad you nerfed it, but in games without Villages, this because useless. That makes it highly situational and potentially very powerful, which is a combination that leads to a type of swinginess.
Gubump with Assassin
Simple and elegant. My first thought was that this is too powerful, since a -1 Card for an opponent is roughly similar to +1 card for you, making this a Peddler variant. But then I calmed down and realized that it only works once per turn. Still might be a bit strong for a 2-cost, but I like it.
xyz123 with Consul
This makes for a cool mini-game where you try to guess which card you need to reveal to do the most damage. Choose too good of a card, and there's a chance that they won't have it in hand at the moment. This may be slightly strong, I'd have to play with it to tell.
