Sorry for the late judging, I've been busy lately.

http://forum.dominionstrategy.com/index.php?topic=18987.msg856103#msg856103A Coppersmith variant that also gives attack protection. I think this is just a Coppersmith without much difference a lot of the time. The attack protection doesn't matter enough to put this above a regular Coppersmith, particularly since it requires keeping Coppers around.
Pharmacy by silverspawn
http://forum.dominionstrategy.com/index.php?topic=18987.msg856107#msg856107This is an anti-trashing attack for your opponents that forces them to get back junk if they trash it. This isn't very good. It has timing issues where you often can't activate the attack when it matters and that creates some feelsbad moments with a 5 cost oneshot.
Drunken Master by LibraryAdventurerhttp://forum.dominionstrategy.com/index.php?topic=18987.msg856118#msg856118A ruin-based junker that gives you a way to mitigate its attack with your own copy. The main issue I see here is that it can snowball, since the first player to get one can somewhat lock out their opponents with ruins, but it doesn't seem like a huge issue. The self-countering nature creates some interesting decisions.
Polish by NoMoreFun
http://forum.dominionstrategy.com/index.php?topic=18987.msg856124#msg856124First impression is that this encourages boring strategies, since it just makes you gain a bunch of silvers to win. Not a lot of nuance here.
Cheshire Cat by gambit05http://forum.dominionstrategy.com/index.php?topic=18987.msg856131#msg856131The attack is pretty interesting, a good mix of punishing, but not so much that it makes games miserable, the command half especially so. It should be unable to hit durations with the attack and the command option, since that makes tracking tricky.
Monkey by grephttp://forum.dominionstrategy.com/index.php?topic=18987.msg856137#msg856137A nice, simple 2-cost card. Not much to say, I like the sleek design.
Beginner by Aquilahttp://forum.dominionstrategy.com/index.php?topic=18987.msg856155#msg856155This is a good concept, but States don't seem like the best way to implement this. It's somewhat confusing.
Prayer by majiponihttp://forum.dominionstrategy.com/index.php?topic=18987.msg856164#msg856164The versatility is very nice. I also like the decisions keeping or using it creates.
Chamberlain by anordinaryman
http://forum.dominionstrategy.com/index.php?topic=18987.msg856165#msg856165This seems like it slows down games, since every single time you gain a card you have to wait for anyone with the states to make a choice and potentially resolve another card.
Planning Committee by Xen3khttp://forum.dominionstrategy.com/index.php?topic=18987.msg856331#msg856331The abilities of this to do megaturns are interesting, but they're sort of awkward. This is more of a pseudo extra turn generator than anything else, so I think it's a bit overtuned.
Midas by Spheremonkhttp://forum.dominionstrategy.com/index.php?topic=18987.msg856401#msg856401Hexes as attacks are pretty underpowered, so this is weak. Best case scenario, this gives your opponents a curse and you get to make $3 per copy of this you have. That's not as much as it sounds because you need two copies of a 5 cost card and they can block it. I think lowering the cost and maybe changing the numbers a little would be best.
Hedonist by mandioca5
http://forum.dominionstrategy.com/index.php?topic=18987.msg856417#msg856417This was super weak at $5, but I really like it at $3. It creates some extremely interesting gameplay. It's a bit narrow, but in a good way.
Genius by Something_Smarthttp://forum.dominionstrategy.com/index.php?topic=18987.msg856435#msg856435I like the concept, but it's a a tad overtuned, not losing it isn't hard.
