Here's what I can tell:
Bot-lane was off to a very rough start, with Karma feeding an First Blood before the 4 min mark. In fact, Karma gave up 5 kills before the 20 minute mark - the most in that phase of the game. Your own first death was just before the 10 minute mark, near Xin taking down Varus. The first tower down in the game was yours, marking a total of 4 kills and a tower for Red's bot-lane, compared to one, possibly two assists for yours. Definitely a difficult early game.
Mid seems fairly dominant early, though it was a slow start. Azir took the first kill in the lane a bit after 8 minutes. Teemo made up for that off of a failed gank, though it didn't help him for long - he died again shortly after. Azir's first death came around the 19 minute mark, to Varus - the result of a roam from one or the other. That fairly well marks the end of laning phase.
Top seems even early on. They seemed to trade kills back and forth pretty consistently, though some went to (and were taken from) junglers. Still, Fiora managed to shove pretty hard - looks like she burned two towers within the first 20 minutes.
Your Junglers were both very active. Amumu managed an early dragon - which I imagine made a very big difference, but both of them were very actively ganking, which is nice to see. Many of those ganks, though, seemed to end poorly for either the laner or the jungler.
Focusing specifically on Azir going forward: His deaths over the rest of the game are sporadic. The one about 19 mins and another just after the 20 minute mark are probably the two closest together, and both look like they happened in large teamfights - in the second, your team broke even. He picked up a few double-kills after that, and traded his next death for a kill on Fiora at about 27 minutes. Around the 31 min mark he fell again, along with Xin. I doubt Amumu took him down alone, though, so it was either a low-kill teamfight, or a rolling-death-ball. My guess is by that point he was trying to keep things cleared, or apply some lane pressure (thus the enormous CS advantage), because he was caught out again around 36 minutes. His last death occurred at 49 minutes, while they were shoving in your base (you lost all three inhibs around the same time).
His build seems reasonable, especially for bronze. I would have recommended a Void Staff earlier than never, and I think Lich Bane would probably have done more for him than IBG - but then again, he may have been trying to deal with Fiora and Varus' massive AD dmg output. I also think the Mobi's may have been a poor choice, as he doesn't seem to've been doing much roaming.
Honestly, if there was anyone in that game (this is the one on 3/28, remember) that I would guess was a troll, it would be the Karma. But I'm not sure I'd even say that with any real certainty.
