Here are my experiences with the different boards. It was a great tournament with really well-designed boards. There are going to be a few themes that recur throughout:
1. Luck on my part
2. Saved by the bell (I was helped out by the match time limits more than once)
3. A, B, and C boards. Certain strategies were either great or terrible depending on what the opponents did.
4. Pile control is tricky in 3-player games
4: Duchess, Peasant, Secret Chamber, Chancellor, Fortune Teller, Remodel, Scout, Woodcutter, Counting House, King's Court, Seaway, Inheritance,
This was my first board in the big round. My opponents were AHoppy and another guy whose name I don't quite remember (David?). Outside of Peasant, Remodel, and King's Court, there's not much here that looks very good. Counting house is good for occasionally spiking a King's Court, but with no trashing, it seems really hard to draw your deck even with Fugitive and a +1 Card token from Teacher. I decided to go for Remodel + Kings Court (though maybe they would have just been better as Golds), but at one point, I did get suckered into inheriting Scouts, which did absolutely nothing for me. I think AHoppy had a stronger deck than me here -- he was also inheriting scouts, but using them to get a large hand that he could discard with Secret Chamber.
Anyway, this game took a long time and ended on time rather than piles or Provines. My Remodels, King's Courts, and Golds put me in a strong position to grab provinces before time ran out. I drew a good final hand and ended up narrowly beating AHoppy.
2: Gear, Duplicate, Horse Traders, Militia, Rats, Transmogrify, Apprentice, Saboteur, Raze, University, Ball
It seems like there are two strong things to do here: Gear+BM+(probably some trashing) and Apprentice+Rats. I chose Apprentice+Rats, choosing not to go for Universities, because I thought the game would go so fast that Universities would be too slow to make much of a difference. The opponent to my left (don't remember his name) didn't end up building a deck that really factored into the equation. The opponent to my right (whose name I also don't remember, but she was wearing a fancy purple dress) built a real nice Rats+University+Apprentice engine. Her Universities ended up being quite important. I tried to be careful with piles, but the opponent to my left grabbed the penultimate Province and then it was over again before it got back to me. I now wonder if Gear+BM is stronger.
7: Forager, Gardens, Jack of all Trades, Mining Village, Throne Room, Treasure Map, Counterfeit, Rogue, Royal Seal, Storyteller
I played this game with Voltaire and Alyse (Roadrunner's mom). Voltaire and I both really had a feeling that there had to be some kind of Storyteller-based engine here (the missing piece was realizing that we could use Storyteller to line up Treasure Maps), but we both ended up going with Jack + Counterfeit. Voltaire beat me by one turn.
5: Poor House, Fool's Gold, Gardens, Rats, Taxman, Thief, Contraband, Horn of Plenty, Hunting Party, Mandarin, Alms, Bonfire,
I played this one with Jordan and another opponent whose name I don't remember. Thief/Gardens is probably the thing to do here, but Jordan was my only opponent to pick up a Thief, and I think he only had one. This opened the door for me to play Hunting Party + Horn of Plenty and get the whole Hunting Party stack. Any fewer than the whole stack, and I think I would have lost. I was able to grab Provinces consistently once I got a Mandarin and narrowly beat Jordan.
Semis:
B: Shelters, Lookout, Smugglers, Watchtower, Spy, Ghost Ship, Tribute, Bridge Troll, Rogue, Hunting Grounds, Prince, Mission, Borrow
I felt like I was underwater pretty much this whole game. Jordan opened with Ghost Ship and Liopoil got an early Bridge Troll. The only way I was even able to stay close in this one was the Smugglers that I opened with and used to copy a bunch of Liopoil's engine parts. Tribute was a key card for him,as he was able to Spy and get an action on my deck and then use Tribute to get enough actions for his engine. I really wanted to build an engine too, but Jordan, the player to my left, was going mostly money, so Tributes would have whiffed for me.
At some point, I spiked a Prince, which I wanted to connect with a Spy, but after top-decking it with Ghost Ship multiple turns to try to line it up with one, I had to settle for Princing a Lookout, which ended up being way better than it sounds. I was able to put junk on top with Ghost Ship and then trash and discard the junk. With a few well-timed Watchtowers, I was able to get some big turns and grab Provinces before time ran out. Without the time limit, I have no doubt that Liopoil would have won this game. His deck was much better than mine.
A: Ambassador, Silk Road, Trader, Pirate Ship, Procession, Cultist, Pillage, Vineyard, Scrying Pool, Familiar, Save, Scouting Party
I was playing Voltaire and Dethwing here and I got stomped. There are obviously a lot of junking cards here and Trader should be an OK defense, but you can't always have a trader in your hand, right? (foreshadowing). I figured at least one of my opponents would get a Cultist, since that's the only real way to draw your deck here. I figured I'd get a bunch of ruins and not even mind that much, because I'd draw them all with Scrying Pool. Fast forward a few turns, no one has a Cultist and since I opened with a Potion, I got my Trader later than everyone else and started getting snowed under with Curses and other Ambassadored stuff. Voltaire discovered Trader/Save and was sailing smooth the rest of the game. Toward the end of the game, I managed to trash quite a few curses and coppers with my Trader and tried to rush victory cards. I somehow came within one of Dethwing, but in reality, it wasn't nearly that close.
C: (No 5/2), Develop, Doctor, Market Square, Oracle, Armory, Bridge, Distant Lands, Band of Misfits, Nobles, Prince, Lost Arts, Pathfinding
My opponents here were shark_bait and iguanaiguana -- they were a riot. I was third player, and after they both opened with a Doctor overpay, I was super nervous that I was missing the obvious opening. I opened with Armory + Market Square (I think) and thought that I'd be more reliably able to line up Market Squares with trashing on a Doctor overpay. I think that was the difference, that plus really bad Doctor luck from my opponents. I was able to get a few golds and spike a Pathfinding, which I used to turn my Market Squares into Laboratories with buy. A turn later, I got Lost Arts to make them into Lost Cities with buy. After that, I grabbed Bridges and Oracles and had enough pile control to grab a Province and empty piles.
Final: Platinum/Colony, Shelters, Peasant (bane), Hermit, Scheme, Watchtower, Fortress, Transmogrify, Young Witch, Band of Misfits, Graverobber, Royal Carriage, Upgrade, Ferry, Summon
I have no idea how I got into the finals. I guess everybody else just beat each other up? Opponents here were Adam and Roadrunner, who is hilarious by the way. The thing to do here is just tricks with Fortress to run piles and grab a VP card before it's over. That's pretty much what we all did, but Adam just did it a little better than Roadrunner or me. Adam grabbed a bunch of Upgrades, while I tried some tricks with Summon+Transmogrify, using Scheme to make sure there was a Fortress on my deck. Once again, pile control is tricky with 3 players. I thought I had left enough cards in the piles, but Roadrunner had a turn between me and Adam, and obviously, he has to make his own deck stronger. So Adam was able to find a way to empty the piles and grab a Duchy -- I was really hoping he would find himself one card short, because I had a hand that should have been able to end it on the next turn.
But I'm not disappointed at all. I didn't feel like I had any business being in the finals anyway. Roadrunner and I tied for 2nd and he convinced me to play a tiebreaker game, even though it was after midnight.
Tiebreaker:
T: Chapel, Stonemason, Market Square, Bridge, Gardens, Ironworks , Talisman, Council Room, Jester, Border Village, Traveling Fair, Ball
Not much to say here. I went for the engine, which I think can win on this board. Roadrunner went for Gardens. After both my opening buys missed the shuffle, I pretty much gave up. Props to Roadrunner. He definitely deserved 2nd place.
I have to say that all the F.DS members there were all great people. Can't wait to run into you all again soon. Thanks to Elestan and ADK for running the tournament!
But I think I've played with enough of the cards (~90%) that I feel confident in saying that after accounting for novelty, it's between Empires and Adventures for best Dominion expansion so far. If you're a serious Dominion player, you won't be disappointed. 
I guess we'll just have to stick with Summon + Transmogrify
