My Group shits on Slaughterhouse and the 4 Horsemen in my honest opinion, but to each his own. Bank Robbers group is pretty dope too. And I think yak pac fatal's group is nice too, except stylistically I dont think Krayzie Bone fits in (other than his flow, but content wise does not fit)
Heres another group I would go with
Pharoahe Monch
Black Thought
Cee-Lo
(no need for a 4th emcee)
Hitler (to rile them niggas up)
Jon McEnroe (to rile the ones that wasn't riled)
Jigga (to handle the rapping part of making rap songs)
Miley Cyrus (SUPER creative + talented + a classically trained actress)
James Baker (to defend the supergroup from the lawsuits of biters and the like)
Crooked I (BEST LYRICIST OF ALL TIME BESIDES SHAQ)
