Great event, I had a blast!
One comment on the missions - maybe don't pair up the Scouring with Hammer and Anvil. It can be really really tough with that much board to cross if you only have 1-2-2 in your zone and 3-3-4 are in the other.
Also, I did not submit a list ahead of time, so here's the 3rd place Necron list -
Destroyer Lord w/Warscythe, 2+, and Mindshackle
5x Warriors w/Nightscythe
5x Warriors w/Nightscythe
7x Immortals w/Nightscythe & Gauss
6x Wraiths w/3x Whip Coils
10x Scarab Swarms
Annihilation Barge
Annihilation Barge
3x Tomb Spyder
Aegis Defense Line w/Comm Relay
