Hmm, I wish I could have been there for this tourney, but I was doing RL stuff. It does look from the rules like the meta would have been fairly restrictive; rationality required 18 fixed cards and 13 fixed quanta, and superstition required 13/31 cards to come from that list, and several of those are very weak compared to the rest. (skeleton, for instance) With the given ruleset, the decks shown look like some of the best. I think that monolight might have done quite well; sanctuary would stop those DBHbows pretty hard, and light dragons/nymphs would provide the hitters, and then some miracles, some rays of light (to get to 9 creatures and bypass the 13 pillar/pend/mark limit on rationality) could have done pretty good.
Just for fun, here's a few speedbuilt ideas that might've been interesting.
Rationals:
Monolight (could use nymphs, but I think they'd be too quanta intensive and they only hit half as hard as dragons)
Fractal RoL/hope (sorta)
Blue nymph gas
Monofire something something
Superstition:
DBH rush
Fate Egg SoR rush: (yeah, yeah, dead skeleton card, but whatever)
