I'm pretty sure anyone can KoG with a Numen Erat Tetsudo deck as long as you are skilled enough. I believe people can climb with Yosenju, Ojamas + Cyberstein and long etc, everything depends on the player.
Not so long ago, someone won the biggest dlm tournament with Darklords, clapping all invokeds, blackwings, shiranui and dark magician.
skill matters
