In keeping with the theme of your deck, I'll suggest the following changes:
Pendulums are a solid choice for any Fractal deck... maybe try switching the MARK to
and changing the Aether Pillars to Darkness Pendulums. That way you're guaranteed to have both types of quanta. Also you can drop a couple Obsidian Pillars.
Another suggestion would be to try to trim it down. 6 Steals might be a bit much. Perhaps, drop 3-4 Steals, 1 Dusk Mantle, and 1 Nightfall.
This will drop the deck size into a nice 31-33 card range. A smaller deck would mean getting the Minor Vampires Fractal'd faster.
Hope you like any of the suggestions.
