Ok, sorry for the long wait. My bad. Better finish this up before isotropic disappears...
It turns out nobody bothered to try the easy mode. Let's do the challenge without the potion then.
Görling got first place with a score of 15. Congratulations!
He took advantage of the simple idea of forging a province into another while using Baron both to buy the Forge and to be forged as the first province. A chapel is used to trim as well. It is probably the optimum play and draw involving this strategy, emptying Provinces in 13 turns with only a Forge and a Province in hand. It would be interesting to know how many times he tried to achieve this, but it probably does not need that much luck. Notably this is also the first submission I received...
chwhite got second with a score of 18: 10 turns with 8 cards remaining in the deck. I don't quite understand his complicated plan (involving Chapel, Menagerie, Watchtower, Ironworks, Mining Village, Bridge, HoP, KC) but the idea is probably to KC-bridge and buy all the Provinces with the Watchtower in hand. The problem is that in the end I believe this strategy needs at least 8 cards in the deck. And it is hard to conceive this strategy can work much faster, if at all.
GigaKnight had a similar idea, finished at the same turn, but with one more card in deck. He scored 19 and went third.
Galzria and
antony went for a Ironworks-Great Hall-Chapel 3 pile. Both need 16-17 turns to end the game without too large a deck and with 3-5 cards left.
Powerman took another approach; he went grand, and hoped to forge the majority of everything in the deck into nothing at the end of the final turn. He finished in 11 turns, but with 10 cards still left in the deck.
A lot of thanks to everyone that participated, and sorry again for the wait to everyone who is looking forward to the result.
Well, there is actually a reason for the wait:
What kind of score are you expecting? My buddy (Görling) got 15 with our idea, you think you'll get answers significantly lower than that?
(I'm not participating, fwiw)
I thought a lower score should be possible. Without getting a better submission, I tried to find one. It was not until today did I get the time to try my idea for a bit:
my solutionIt involves the famous Chapel-Ironworks-Great Hall-Island 3-piling, but one still needs a way to trash fast enough to have a small deck in time. I include Fishing Village and Watchtower to help. The idea is first to use the in-hand Watchtower to trash the hybrid VPs when you gain them to ease the burden on Chapel, and second use Watchtower to draw fresh when using the IW gaining IWs . I finished in 12 turns with a 3 card deck. It ties with the elegant forge solution.
The play is not entirely optimized, but I have already spent an hour playing. Mining village may be better than the Fishing Village here as well. So at last... we have a complicated solution that is at least as good as the elegant one by Görling.
