Situation: Trashing Estate into a 4$ with Farmland
What you think you've done: Getting rid of Estate and gaining a great card instead.
What you've actually done: Maikng your Estate worth 1 point more and buying a 4$ instead of 5$ or Gold.
I think MANY people don't get this one...
But you've "made your Estate" remodelable (or Farmlandable) into a Province. So it's not as bad as all that.
Exactly!
I think a lot of people actually don't appreciate how much faster Farmlands can make a deck. Suddenly, you need $6 to start on the Province run, rather than $8. Also, marginal VP gains = tiebreaker in a 4-4 province split.
Farmlands is a card that I initially thought weak, but with time am beginning to see as an essential buy whenever it turns up. Unless there really is an incredible power card at $5, or my deck doesn't have a couple of golds yet, I'd almost always advocate getting the Farmland and changing the estate to a useful $4. What has actually happened is:
...+1 VP net total, ok not great, but every point counts.
...the card slot that was dead from being occupied by an estate is now occupied by a useful card for any trash-for-benefit, and we know that there's at least one trash for benefit card in the set: Farmland. If there's other trash for benefits in the Kingdom, then Farmlands becomes even better!
...a $4 card has been bought.
Compare this to buying a $5 card:
...a $5 card has been bought.
And that's it.
Farmland suddenly looks quite appealing, though obviously the real deciding factor is how much better a $5 card in a given kingdom is than a $4 card.
But as a rule of thumb, I think Farmland, a good card gained and a bad card trashed is worth way more than most $5 action cards
Buying a gold, OTOH, is very different. My general observation is most people don't buy enough gold. In the early to mid game Gold is probably better than Farmland + a great trash (i.e. okay $3-> great $5). In the late game, once you have enough gold in deck, I'd strongly advocate the Farmland if it gives even a slightly worthwhile trash.
