@Silverspawn : Yeah, sorry my post came out weirdly. I totally got your point about the fact that having a discard pile is not reliable, but was wondering about the power level at the same time, so it got mixed up. Your post was helpful, though.
If we compare it to Herald, at first both seem to have the same problem : if you don't have a discard pile when you buy herald, you can't use its top-deck power. However, even if you don't have a discard this turn, if you play an Herald, there's a chance that you'll pick an Action card on top of your deck anyways. So there's a way to get that +2 Cards +2 Actions.
Now Forest Village... Like you said, sometimes you just won't have a discard pile, especially because if you have an engine which can draw your whole deck, it's all gonna be in your hand. The obvious way to solve this is to be able to discard some cards, in which way you get +1 Card +2 Action - you play the action card you discarded, you pick a card and +1 Action too. The power comes from the fact that you can choose exactly which Action card you're going to play.
We're getting something here, I think : Forest Village looks bad with an engine that can pick your entire deck, but it's actually pretty good, since you'll make sure that, even when you start greening and you can't draw your whole deck, if you have a way to sift (Storeroom, Cellar, Warehouse...), you'll probably be able to play exactly the Actions you want to play.
So it's definitely not ''flip a coin, hope you're lucky''. However, I'll keep your opinion in head while playtesting it, just to make sure (after all you're more experienced than me).
@LastFootnote : Yeah, good idea. If we make the discarding optional, playing it from your hand or the discard is pretty much the same. However, I think I'll try pacovf's idea of making the discarding compulsory, in which case that doesn't work (if you have no Actions in hand other than this, you still need to discard a Treasure or something).
@pacovf : Excellent idea, I'll try this.
Ok so I now have two versions. One at 4$ and one at 5$.
Forest Village
4$ - Action
+1 Card
+1 Action
Discard a card. Look trough your discard pile, you may immediately play an action card from it.
Forest Village
5$ - Action
+1 Card
+1 Action
Look trough your discard pile. You may play an Action card from your discard pile or hand.
I feel like the first one will be extremely powerful with Torturers or cards like that, but the compulsory discarding might be just annoying enough in the early game to balance it. The second one solves this by competing with strong attacks at 5$.
