HQ: 2 CSM Sorcerers with Lash
Troops: 2/6 man CSM squads with Melta in Rhino with Combi-Meltas
Elite: 1 Chosen 5 Man Squad in Rhino with 3 Meltas and 1 Flamer
Heavy: 2/2Obliterator Squads
Run the Sorcerers with the CSM rhinos and use the lash to create targets for the Oblits. Then have the Chosen as the finisher.
Don't know if it has enough units in it and might get overrunned by hordes but it might be cool.
