My take on this was either use my smackin nobz combo, or take a doomsday ark or doomscythe, it would instant death the nobz and the wouldn't be able to get an armour save or feel no pain, and then for added lulz add obyron or overlord (overlord probably less risky given he can take a 3++) and then challenge his ass.
Me: To be honest im amazed there isn't a chaos god of not revising or at least chaos god of procrastination
MidnightSun: There will be, when enough people do it. Y'know when the Eldar were all engaging in their hedonism and Slaanesh ripped open the Eye of Terror with his creation? Slaanesh will have NOTHING on the God of Procrastination, and his vile minions will carve the galaxy asunder in a thousand year reign of blood.... Tomorrow
