Deck idea came to me while looking thru my trade binder at good cards that haven't had a chance, but may yet still shine in Standard. As the name implies, the deck primarily uses E and demons for various effects, mostly tutoring and removing threats alongside Liliana to re-an our threats:
Deck plays control in the early game removing threats, but goes more midarange as the game continues. Card Advantage/Card Draw come in the form of Cycle cards Canyon Slough, Razaketh's Rite, and Glint-Sleeve Siphoner.

CARD CHOICES
Weaponcraft Enthusiast: Quite possibly the most important card in the deck. 1) Provides bodies that can be sacked to Razaketh, the Foulblooded's activated ability. 2) Provides 1 to 3 E for us via Decoction Module and more bodies to produce E via Demon of Dark Schemes should they die. 3) Produces servos that almost guarantee Unlicensed Disintegration deals 2 damage to our opponent each time we cast it. 4) Can be re-aned by Liliana, Death's Majesty for repeatable effect. 5) Produces servos that can be used to Improvise Herald of Anguish's CMC, getting Herald onto the battlefield much sooner.
Decoction Module: E engine of the deck and Improvise CMC for Herald.
NOTES
-I think 24 lands should be good enough, but may go up to 25 after getting more testing in.
-Need some help with the sideboard. It's stocked with "more-of-the-same" removal-type spells, but I think it could be even more tuned.
That's it for now. Suggestions/Criticisms welcome!
