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
![Aether :aether](https://elementscommunity.org/forum/Smileys/solosmileys/../../../images/Misc/aether18x18.png)
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.
