You must have very powerful strong deck like Blue Eyes White Dragon and kaibaman to quickly summon and destroy any monster and champion's vigilance to negate any summon and hit his LP directly ....... It is hard but not impossiple ..... I defeat him easily :D
I used a 20 card deck with balance. Lots of high attack level 4 monsters and the only trap cards being straight flush. He fills his spells zone almost every turn unless he goes first and you can wail on him if you use 1750 or above monsters.
