Jack decks do very well against greening, but maybe not quite as well as a dedicated venture deck. That said, your opponent did not build a dedicated venture deck. And as WanderingWinder pointed out, DoubleJack should beat Jack/Chapel pretty handily, and you should be able to simulate that to check.
I think this illustrates a larger point. Most people who read this forum know that chapel is one of the strongest cards in the game. But they tend to forget it's only because of how good it is for engine games. It's mediocre in big money games, losing to quite a few cards head to head. The reasoning is simple: spending turns doing nothing but trashing slows you down and you need some way to catch up. Usually this is with a big engine with multiple buys. A dedicated big money deck doesn't waste those first few precious turns trashing.

. That said Ventures are extremely strong with Chapels, but she only bought 2. I don't think it was the deciding factor. LadyFern is a good player, but I think she had a bit of luck on her side here. I imagine Jack has a 60/40 advantage here (maybe a little bit higher), but sometimes the better plan loses. It's the only $2 with a +Buy.
You forgot Pawn. Which should be able to replace Hamlet in the solution. Herbalist also has +buy, but wouldn't work for this.
If you're smart, you buy gold...
But also, there are many known turn 3 province things. There's a whole thread...
$6
Worth 1 VP for every 2 Coppers in your deck
This version introduces some tension: You want a lot of Copper in order to boost their value, but flooding your deck with Copper actually makes this card harder to buy (unlike the $4 version), so you have to thread the needle of boosting your Copper density, but not so fast as to make the $6 victory card unaffordable.
Thoughts?

Hell, it could even be
1 Swindler: Swindling the opponent's $5 action card into a Duchy (action card stack was empty, no other $5's around) and his 8 Silk Roads hit another VP target, so this gains him 8 + 3 = 11 VP. Since Sarah was already 1 point behind, the best she can do with her 1 Buy is buying a Colony for "just" 10 VP, still 2 VP short of a win/tie.
Least:This is most probably a Chancellor/Stash board.
$6 Adventurer
$5 Counting House; Stash; Harvest; Cache; Explorer
$4 Navigator; Coppersmith; Bureaucrat
$3 Chancellor
I buy 3x as many Navigators as the population. Otherwise this looks a lot like my least-buys.
Again, this is a Counting House board; else just straight Big Money.

Perhaps they were worried about the ContrabandOr his Ill-Gotten Gains.
Unfortunately, Hinterlands makes even this house rule a pain to implement. We used to play our first two hands at the same time. You draw your first hand, see that you have 2, 3, 4, or 5 Coppers and then choose your first two cards and shuffle. That shaved a little time in the grand scheme of things, and it wasn't that big of a deal in terms of seeing what others buy first (in our group anyway).
Hinterlands changed that. If you buy a Mandarin, Noble Brigand, or Nomad Camp in your first hand, you no longer can rely on having a 5/2 or 4/3 split.
So, mirrored hands of 5/2 and 3/4 are not specific enough. Now, you would have to mirror CCEECECCCC or CCCCCCCEEE.
Unless you're willing to go through and stack all the decks the same after revealing one, mirrored hands may not work out anymore. It'd be fine for Isotropic, of course.
