Wow, I had a great time. Got some EDH in waiting for the event to start. Tourney ran without a hitch (despite some concerns about DCI Reporter), and having lunch delivered during my Bye was pretty awesome.
The meta was, as I saw it (15 players total):
1+ TPS
1 BUG Fish
1 GW Fish?
Lots of Tezz and Tezzeret-less-Tezz, Remoras
1 Metalworker Combo
1 Mono Red Shops?
1 5C Shops
And one person playing Oath... me.
Here is a bit unconvential Oath build, since I wanted something fun for a birthday party.

The deck was a blast to play, as it does some crazy things (I played Timetwister 5+ times in 4 rounds of play, though mostly that helped my opponents). My opponents and I reached a lot of complicated and interesting game states. No, it isn't as good as having Iona main, but it's not that bad.
The deck completely dodges Null Rod, and Thada Adel, and taking out Mana Crypt, Tinker, Robot, TV+Key gives one a bit more room to work with, though I didn't end up with anything more exciting than Impulse for the 59th and 60th cards.
Some notes after playing:
-Nature's Claim is amazing.
-Spell Pierce disappointed, maybe this is because my opponents were always seeing their Tolarians, or because half of their combo was Metalworker.
-Jace was pretty sick. I'm not sure he should be a 2-of, but I wouldn't play Oath without him. I did get to put an opponent's Demonic Tutor on the bottom on their library, so he definitely staved off defeat in that game in a way FOF or even Gifts may not have.
-Chain was decent even without Swans, killing Dark Confidants, Metalworkers and once an opponent (well, so I put him to one with a Confidant trigger on the stack).
-Energy Flux was really good... most of the time. As I said, my opponents seemed to always have Tolarian, or played some {5}CC artifact that made us skip our upkeeps. They probably won me two games on the day.
-Gaea's Blessing would make comboing easier, but is so bad when you draw it. If I do go up to 2x Jace then I may reconsider it.
-Recoup may deserve a slot. If you Oath too far you're basically dependent on Regrowth/Timetwister/Yawg, and losing Lotus hurts those plans tremendously. Recoup doesn't really help with that problem, and may be worse than Blessing.
-Terastodon deserves a sideboard slot. I really hedged against Dredge out of habit, but if I had chanced it with just 4x Relic then the Planar Void slots would have been Terastodon and Red Elemental Blast. It would have helped tremendously against Shops (at least the one I played, where blowing up Shop/Staff would have been nice). Alternatively, Terastodon could replace Archangel.
The 15$ credit from 5th-8th mostly paid for Phyrexia vs. the Coalition, which I was surprised to find contained Living Death, in addition to the Voltaic Key that I wanted.
Thanks to my opponents and to Myriad/ELD for a great event.
P.S. Pic of the Ruby I picked up coming tonight. It's a beaut.
Edit:

My new Ruby, in there with the reasons why I played Oath (well, and I had this sweet brew). Apologies for the phone-camera quality.
