I agree with sSethia. The only time that a fractal would be a good idea for aether-mono is if its used on a spark or ball lightning. If you were thinking of fractaling the spiders that's just a bad idea since fractal uses up all of your aether quatna.
Well, it is not so bad idea, a fully upped monoaether with phase shields, spiders and fractals can beat some false goods if you knoww to time it. You have to stall with phase shields until you have +13 aether towers more or less., in the way, if it is a good without healing, you have done some damage by playing some spiders. And when you have the towers, fractal it, and next turn you can play 4 or 5 of them. And keep doing that. Not good for score because the winning percentatge is low, because you can't win some goods and it is dependant on draw order of cards and also, never makes EM. Having said all of this, is a deck that I don't like, because you never now if you are going to win, it's all the games a race, a bit stressing.
