Here's my current 1850 list for tournaments. I'm still a little iffy on what to do with my HQ's beyond a single Doomseer (pretty much compulsory in every list I build.) Input and ideas appreciated.

Tactics:

Farseers ride with the DA's Dooming and Fortuning to ensure they live and kill what they're supposed to. Warp Spiders support either the mechanized DA's or sit with my anvil. Wraithlords stay with the Harlequin's serving as anti-tank and counter-charge (the Shadowseer prevents their Wraithsight problem.) Rangers sit on my home objective or infiltrate to good cover depending on the mission. Jetbikes snipe and turbo-boost for turn 5 objective grabbing.
