Sorry for the late reply; time to close this contest without the usual 24h warning! The activity seemed promising at first, but then it fell off completely after december the 20th, resulting into 4 submissions to judge. I really got a feeling this contest isn't very popular anymore. Anyway, judge time!
Wild Plains by BryGuyWild Plains (Action - Duration, $5)
+1 Card
+1 Action
+1 Buy
Now and at your next Start-up, reveal your Deck's top card, you may discard it. If it is a Horse, gain a Cavalry; otherwise gain a Hostelry.
Wild plains is a strong Village gainer, as you can always forego Hostelry's on gain effect, leaving your deck Horse free and make it always gain a Hostelry. The other card, Cavalry, looks pretty painful to get. Especially the first one, as you have to fully count on the Horses that came with the Hostelry. In the most boards, getting the Cavalry as opposed to Hostelry will be mostly be a happy accident. This means that whenever the Hostelry pile empties (which will be fast), Wild Plains will mostly be a glorified Market Square. I don't think it is that interesting to play with tbh.
Swill by DominionaerSwill (Action - Duration, $4)
If this is the first time you played a Swill this turn, at the start of your next turn, discard the top card of your deck. Gain an Experiment per $3 it costs (round down).
As Faust kindly pointed out, gaining an Experiment is the same as gaining 2 horses. Gaining 2 Horses is preferable unless you really want to make use of the fact that there are only 10 experiments in the game. Your submission doesn't seem to make use of that at all. Looking past that, Swill looks absurdly weak; possibly even worse than Scout. Certainly not a winner for this contest.
Models by Will(ow|iam)Models (Ally)
At the start of your turn, you may spend 2 favors to gain a shanty town to your hand.
Models is a pretty clever idea for an Ally. It is mostly an ally that makes you wanna have enough Favors at the start of your turn, because in a hand full of terminal actions, or no actions at all, Models is going to be quite helpful. The only downside to this submission is that in a competitive setting, the players may have too few Favors to spend and there may be too many excess Favors to be earned (though I guess several other allies share this problem as well). I'm kinda split on whether this should've been a Project instead.
Farrier by emtzalexFarrier (Action, $5)
+3 Cards
You may play a Horse from your hand. If you don't, you may discard a Treasure to gain a Supplies.
This looks like it's making for a pretty self contained drawing engine. In most Farrier games, Supplies will be the only Horse gainer, so all Horses that are in your deck are already in your hand before drawing Farrier; you just hope that you can draw Farrier before spending your last Horse. As such, playing Farrier non-terminally may be somewhat tricky. But that's okay; a Smithy that can generate Supplies is already worthy of the $5 price tag. Playtesting needs to be done to see if this is broken or underwhelming or alright, but the submission seems pretty well thought out.
VERDICTThis leaves us to the winner and runner-up. It was extremely close; almost interchangeable.
Runner-up: Farrier by emtzalex
Winner: Models by Will(ow|iam)
Congratz to Will(ow|iam) for winning this contest and good luck hosting next week's contest. If you have no idea for the next week's contest, you could also do a season's finale.
