I've actually just came up with an idea I'm hoping someone has tried this before, not sure which would be better but both similar.

The idea being you deploy reik, gos, the harrow, reapers and depending on list the 5 hexwraiths or the black coach. Then set up the banshees, bladegeists, spirit torment, any remaining hexwraiths in underworld. Turn 1 cast cogs with reik, gos cast tempo on its self to get extra 6 move. Harrow warps 9 away from enemy, and summons the 30 reapers to its side, reik, black coach and hexwraits already have good move and cogs and pendant help here too they all run if they need to down mid, then deep strike the banshees, blades, spirit torment, hexwraiths again depending on list and go all charges, and surely that's opponent surrounded turn 1?
