I built a few more decks than this, but these are the ones I used:
spidertal wings 1-0

-round 2 game 2 vs xyan WIN vs dragonfly/dragon/fractal wings (very close game) I won this game by a single turn. I ended up fractaling his dragonflies and then his dragons, because his wings kept me from doing any damage. I had 0 turns left on my wings, and no more in hand (the last 4 were bottomdecked) so I won literally in the nick of time.
PU dragon blitz 2-0

-round 1 game 2 vs eljoemo WIN vs quinted spider/wings (saved up dragons/PUs and a blitz and got past the spiders/wings that way)
-round 2 game 1 vs xyan WIN vs NT water/entropy duo (won because I got 3/4 lightning for entropy nymphs, would've lost otherwise)
water/eternity stall 4-1 (This was easily my favourite deck of the day, and had I won a mark today, I'd have taken a mark for this)

-round 1 game 1 vs eljoemo WIN vs earth deck w/aether mark (I don't know what aether cards he had. I used my golden nymphs and he didn't have any in hand; I assume he was using lightning, though. I saw gnomes and shriekers)
-round 3 game 1 vs serprex WIN vs entropy/aether PU/dragon lightning (had he done air/aether and used sky blitz, he probably could've OTKed me at some point, but entropy/aether didn't have enough creatures)
-round 3 game 2 vs serprex WIN vs NT entropy/water (not much he could've done here)
with -1 eternity +1 procrastination (at serprex's suggestion)
round 4 game 1 vs kakerlake WIN vs mirror match (I got more icebolts for his eternity than he did for mine)
round 4 game 2 vs kakerlake LOSS vs aether/air fractal spider/dragon wings duo (If I'd had a seventh icebolt... I ended up losing because his lobo killed me. If only I'd found room for purifies to heal...)
nymph gas wings 0-1 (chosen mostly to be unpredictable)

round 4 game 3 vs kakerlake LOSS vs aether/air duo (He got a quick lobo and I had only 1 NT to start, didn't find a 2nd until more than halfway through my deck. I might've had a chance had I managed 2 quick NTs)
