Clockwork Steed looks bad compared to Caravan,being a twice delayed Lab.
It's also vulnerable to handsize attacks in a way Caravan is not.
Faerie Ring is overpowered. We know how strong Druid is with Swamp and this is nonterminal.
It also costs double what Druid does (and--with rare exceptions--always requires the bigger half of your opening split, while Druid always takes the smaller), doesn't provide +Buy, and doesn't trigger the WoWs when it's revealed. The fact that it eventually turns into a potential source of payload certainly is a big benefit, but I'm not sure it's obviously busted.
Here are a few of my own thoughts:
For the cards that say "Do this twice: Choose one: ..." I think you could just say "Chose two:... (You may choose one option twice)." While it's probably longer, imo it's less awkwardly worded.
Small Bazaar feels a bit too strong to me, especially when compared with Town (which I already think is one of the stronger villages). Although you lose Town's +Buy on the money option, you get the +1 Card
and (more importantly) you get to see the card you drew before having to decide if you want Actions or $. This lets players draw without a risk of terminal collision, then take the $ if they didn't draw an Action card.
Hidden Village would have some real challenges in terms of accountability for IRL games. Basically, if you had one in your deck you would have to look at each card you drew before combining them with the rest (to see if it was a HV). Otherwise, your opponent(s) couldn't be sure you weren't attempting a slight-of-hand to play an HV you already had in hand.
The "On your next turn..." language in Seawall is a bit awkward. I'd phrase it as something like "At the start of your turn, put the set-aside cards into your hand, then set aside two cards from your hand."
