I played in 3 'flights'.
1-1-1 in the first one (played red), 1-2-2 in the second (played black), and 4-0-1 in the third for first place (played white)!
My deck list for my first place deck is as follows:
Land (17)
Plains (9)
Forest (7)
Temple of Mystery
White (12)
Banishing Light
Chosen by Heliod
Dauntless Onslaught
Dawnbringer Charioteers
Dawnbringer Charioteers
Eagle of the Watch
Gods Willing
Lagonna-Band Trailblazer
Oreskos Swiftclaw
Oreskos Swiftclaw
Sightless Brawler
Stonewise Fortifier
Green (9)
Colossal Heroics
Desecration Plague
Golden Hind
Golden Hind
Pheres-Band Thunderhoof
Setessan Oathsworn
Snake of the Golden Grove
Voyaging Satyr
Vulpine Goliath
Multi-colored (1)
Ajani, Mentor of Heroes
Artifact (1)
Gorgon's Head
Banishing Light and Desecration Plague overperformed, while Sightlesss Brawler underperformed. I didn't pull Ajani until my 5th match, and he was great!
I also pulled a Kiora in the 'flight' which I chose black, so I ended up playing a 3-color BuG deck which didn't do great, partially because the deck played rather slowly, and I got paired up against 2 durdly opponents, whom I could have beat if I had just had more time.
