OK, I've a game Thursday (probably against Giants) and I think I've settled on the below. No idea how I'll get on but the only way I'll learn is by trying! Any c&c greatly appreciated.
Scarlet Doom
1950, 1 drop, Hold the Line, charge triumph
Lady O: Shademist – 340
Krulghast – 150
GoS: Midnight Tome, Seal of Shyish, General: Ruler of the Spectral Hosts – 150
30 x Bladegheists – 525
30x Chainrasp – 330
3 SH – 125
3 SH – 125
Hex – 160

If can, go 2nd and fish for double turn 1-2.
Chainrasp and GoS defend backfield and auto cast cogs.
Lady O to target midfield with 1xSH, offering support.
Bladegheists to deepstrike with KGC and 1xSH offering support, the latter tanking for KGC
Hex running around doing stuff.
