I had four stalls that I built for today. I'm quite sad that looking at the decks posted, I think I could've beaten anything that anyone has posted so far. The only two things I was worried about in this meta with any of my decks were firebolt OTKs and earthquake/trident, and that's what I went against in games 1 and 2 :p I still don't know how Vangelios managed to get a flying quinted trident out with a 60 card deck before I could play the earthquake that I had in my opening hand on his quantum pillars, but... that's how it goes sometimes :p I think I had the advantage in both matchups, but I missed my enchant artifacts and emerald shield in game 1 that I needed, and my pillars and EAs in game 2.
I had "the deck" (lots of CC/PC, modded for this environment), firestall (4 lucis, and UG/shockwave/nymph from air), a 60 card disquake, and a water/light stall that had toadfish for attackers and air pends to meet the air requirement. I also used an anti-rainbow deck I speedbuilt in game 2 for Vangelios, but, as I mentioned above, bad things happened to me.
I like Calindu's immorush. I couldn't think of any fast decks that would've worked in this tourney, but that one looks like it would've been successful on a good draw. (I still think I could've beaten that, too, except with my disquake, which would've probably lost horribly to it) I always have bad luck with immorushes, though... :p
