First of all, the shards of readiness and the nymph make this deck not available to many people; second of all it is to large to be optimal. The ball of lightnings are just plain pointless. As for the fractal, what are you going to fractal? In conclusion, this is a mediocre deck that just don't shine very much.
Don't get mad at me for these criticizens, you asked for comment. 
I assume the plan was to fractal ball lightnings for a quick damage burst. Also, i believe he posted this deck mostly for improvement suggestions because he owns those cards, so rarity isn't a problem. As for deck size, i agree that it is too large. The number of pillars is also an issue. You have lots of high cost cards (TU, phase shield, fractal, nymph) and only 11 towers. I would suggest you:
1) Remove the SoD. It's not that great tbh.
2) 1 SoG won't do that much. I'd say either remove it and add more shields or add more SoG's
3) If you are going to fractal the ball lightnings, you don't need so many, just keep 1 in your hand after you fractal it. Then you can take a few of those out. If you don't fractal them, i don't really see what makes them that much better than lightning, so i assume you fractal them.
4) aether nymph, is it really worth it? maybe it is, maybe it isn't, you decide.
5) SoR, is it just there for the TU'd creatures? for the nymph? either way, I don't see it being all that effective.
