Had the opportunity to play in both Saturday events and the early Sunday event in Louisville. Between the 12 rounds I managed a 9-2-1(ID) record (played the draw match for fun and won 2-0). Played against:

White Eldrazi
UW Landstill
Stax
Oath
Dredge
Esper Mentor
B/W Hatebear
Outcome Mentor
High Tide
Car Shops
2 decks I can't remember

The losses were to the Stax list where I tinkered away my Seat of the Synod for Jar turning off my Mox Opal. I had enough mana in hand to play Vault/Key that came along with it through a sphere, but needed the Opal to be turned on.

The other loss came to the Outcome Mentor that went back and forth but, I was always a Force short of winning or stopping him from winning.

Here's the list I played.

Black Lotus
Mana Vault
Mana Crypt
Lotus Petal
Mox Emerald
Mox Jet
Mox Ruby
Mox Sapphire
Mox Pearl
Sol Ring
Grim Monolith
Voltaic Key
4 Mox Opal
Chrome Mox
Sensei's Divining Top

Time Vault
Aether Reservoir
Tezzeret, the Seeker

Merchant Scroll
Tinker
Transmute Artifact

4 Paradoxical Outcome
4 Gitaxian Probe
3 Thoughtcast
Ponder
Ancestral Recall
Time Walk
Mind's Desire
Windfall
Timetwister
Memory Jar

2 Repeal
4 Force of Will
Chain of Vapor
Hurkyl's Recall

Tolarian Academy
3 Seat of the Synod
3 Island
3 Ancient Tomb

4 Grafdigger's Cage
3 Defense Grid
2 Hurkyl's Recall
1 Chain of Vapor
1 Rebuild
2 Mindbreak Trap
1 Flusterstorm
1 Blightsteel Colossus

@myk Thank you for the report.

The most unusual card in the list is the Aether Reservoir. Could you perhaps elaborate on the reasoning for it's inclusion and how it played throughout the game.

Also, the Paradoxical Mentor player wasn't by any chance JD Nir?

The thought behind reservoir is with increasing amounts of decks that are pressing the board this would buy me time and also serve as a win condition over the course of a game whereas something like tendrils typically has a small window for you to play it in to actually win. It also serves as a win condition that can't be Flusterstormed like tendrils. I was able to win 4 of 5 games with it in play throughout the weekend, but typically the wins were via vault/key and if the opponent asked for the win condition i would just show the tezzeret.

Yes, jd nir was my outcome mentor opponent. While i stated that the games came down to whoever had countermagic to hit the big spells his Top was putting in overtime allowing him to find his countermagic in crucial spots. But like i stated in original post, they were back and forth, pretty intense and well played games.

The sideboard is something that I want to toy with more, perhaps getting something like Propaganda in there to slow a creature rush and buy me more time.
