I played my first game with the new Dex earlier in the evening against our wayward kin.
Archon with Huskblade, soultrop, shadowfield, Portal
Venom with Splinter cannon
Voidraven with Dark Sycthes and Night Shields
Razorwing with Dark Lances and Night Shields
Dark Artisan Formation
Haemonculus (warlord) with Portal & Syndriq's Sump
Chronos with spirit probe and Vortex
Scatter laser, Shuriken Cannon, holo fields
I played my first game with them tonight against Eldar using a tournament mission he wanted to try out. 5 objectives. You scored them at the beginning of your turn but could only core them once so there was fierce fighting for control throughout the entire game.
The Dark Artisan formation was nastier than I expected. With the warlord trait they rerolled 1s on FNP and were able to eat through a wraith knight, 3 spiritseers, and a squad and a half of wraithguard. I did make some incredible IWND rolls gaining 3 hit points back on the Chronos, 2 on the Haemonculus, and 2 on the Talos.
The Archon deep struck in with the a wave serpent full of wraithguard. They killed Eldrad with some nasty distortion rolls and capped 2 objectives but didn't get to do much else.
The venoms and warriors soaked up a ton of damage during the first two turns killed off two squads of warriors, 3 venoms, and 1 hull point off the last one.
My 3 flyers were up against a single Crimson hunter exarch that I kept making saving throws against. It pretty much left my flyers unmolested so I could roam around hunting his wave serpents. I ended up tabling him at the end of turn 5.
Final Thoughts: The web way portal allowed me to drop my nastiest units in his face which freed up my flyers and my remaining warriors/venom to hold objectives. Objective secured preventing him from scoring one objective all game and forced him to throw a lot more at the other than he wanted to.
