I am dying to do a tourney and think I have a pretty sweet list for it
2 DPs Nurgle Wings Warptime
2/3 CSM bikers squads: 2 meltas and Champ with Pfist
4/5 CSM squads in Rhinos with 1 melta and combi-melta on champ
1/2 oblit squad
i have also pondered making the DPs Slannesh with a lash and WT, dropping the combi meltas and then adding another obliterator.
