The idea is to chain Nightfall as much and as often as possible. Capitalize on the gas and ping provided by nightfall. Break the symmetry of life loss with, Lunar Magus, and Lumen Defender. Majority of the units have deadly, so might as well thrown in spiders and torrent.
Nightfall engines:
Lastlight Infusion
Gloaming Wisp
Nocturnal Creeper
Unseen Agent
Lunar Magus
Baying Serasaur
Amethyst Waystone (conditional)
Miris Nightshade (conditional)
Occasional Life gain engines to break symmetry:
Lunar Magus
Lumen Defender
Comments on matchups:
You can possibly draw the wrong side of the deck by drawing your non-nightfall engines during the early parts of the game. In this case you can survive on life gain for a while but the main plan is to be aggressive enough with nightfall. Does 50-50 so far in the matchups I had. The deck is funny when it works though.
Comments and suggestions on improvements are appreciated, (seriously). Thanks!

For added aggression, I've tried Baying Serasaur. So far it's doing good in a nightfall aggro shell like this, being a 4/4 everytime you have nightfall on, and that's most of the time.
Removed dredgers as they haven't been performing as expected, them being a lightning rod for removal once they come down, they really die too much. Swapped out arachnophobia for lastlight infusion for nightfall engine and unit boost. Also reduced Miris count, she's aggressive but most of the time you'd want to trigger nightfall instead. Her being a 2 of means you'll see her most of the time when she's immediately able to ulti and trigger nightfall.
Anyway thanks for commenting!
