Hmm, Trafalgar has his Room with which he pretty much cut an entire island in half. I don't see how Madara's going to get around that, in fact I don't really see how anyone can beat Trafalgar because we haven't really seen any weakness to his technique yet as far as I can tell. Madara doesn't have haki to shield himself either and all of Madara's attacks could be easily sent the other way once they enter the room and if Madara enters the room, then he's really boned.
I think I'd like to see if Trafalgar's DF has some real weaknesses because it seems pretty OPed at the moment. I think haki shielding may its weakness but Madara doesn't have that anyway.
