There is no way you're going to get enough aether to manage to spam dim shield AND fractal in time.
I would consider using another kind of shield other than dimensional.
Skull shield isn't terrible, ice shield is amazing, don't underestimate the common shield.
You're not going to get out those chrysaoras on 4 pendulums either.

This deck isn't too great either, but it seems to be an improvement;
I question how good a target chrysaora is for fractal.
