OK, I've done a little testing. I think I have a solid value list — no real tricks, a couple toolboxes. I have no byes for the GP so I will definitely be playing round 1. So I'm expecting to see burn, dredge, elves early.

Marsh Flats
It is 61 cards. I could probably cut the Marsh Flats. Vault was the 61st card, but I really love it against the burn decks that I feel like will be endemic throughout the tournament. I actually thought about Diamond Valley, but it doesn't produce mana, and Miren requires you to have 3 mana + a creature on board which isn't all that different than Vault anyway. Plus, there's lots of neat tricks and you can gain a lot more life with Vault.
Where I'm stuck is the sideboard. These are the cards I want to have:
3 Thoughtseize
3 Nihil Spellbomb
2 Pithing Needle
It's worth respecting combo decks and graveyard decks. Needle is also a nice catch-all.
Then I'm wondering about these:
1-2 Gaddock Teeg (Obviously I want this in for trouble matchups. Not sure if I want to have the extra in my pocket though. Not coming in vs. Cruise at all)
0-1 additional removal (Abrupt Decay, Maelstrom Pulse or Council's Judgement. Or none.)
0-1 additional disenchant effects (Pridemage, Reclamation Sage, Krosan Grip. Batterskull is annoying...)
0-2 additional sweeper (Deluge, Deed, Charm. I would lean toward Deluge to hedge against opposing Pithing Needles.)
0-2 Planeswalkers (Probably Liliana of the Veil. Sorin, Lord of Innistrad is the only other one I would consider. Didn't like any of the Garruks vs. Miracles which is a key reason I want a PW. Lili clears their board but doesn't win the game. Sorin goes up in loyalty to make dudes then steals their Jace. Both -2 abilities are irrelevant.)
0-1 Scavenging Ooze (I had this in the main but went with a 4th DRS instead. While Scooze is more of a blowout against dredge it's luck or a GSZ turn which makes it pretty unreliable.)
0-2 Carpet of Flowers (I think a PW is better against miracles. I should be able to make land drops and with 4 DRS can still do t1 dork into t2 must-answer play)
I have decided that I don't really care about a resolved Treasure Cruise all that much. We are an x-for-1 deck so with patience, luck, and planning for how decks with Treasure Cruise use it, it should be largely irrelevant if they draw more cards. Nice Forked Bolt, I have a Siege Rhino, you know? I'd rather just go over the top than play cards that actively screw with our own game plan like Teeg in the main or that require a significant time and mana investment like Scooze just to keep them from drawing more cantrips eventually. Deathrite can control their GY a bit while clocking them or gaining life.
The only other thing I am trying to decide is 3rd Deed/2nd Charm/1st Deluge vs. 2nd Sylvan. Sylvan is so good, even if it's deeded away. Just drawing one extra card off of it can swing a game immensely. But I see most lists have 3 sweepers and 3 library manipulators. Charm is a meta call, it hits the YP and Elf armies for no life (and for 2 mana). I want to keep the curve somewhat low too and run 3 Decay, it's just a hammer. Not hitting TNN sucks, but it does deal with other annoyances like Goyf.
