This worked well. Just keep destroying his defense monsters. Get a tribute with seer and another monster. Use dian keto and 3sd to get to 1000 lp on last turn and hit him for over 10k. Have to just hope he doesn't deck out faster.
I think it only costs 3k in pvp. Its still 2k for ai. In the times i used this he didnt seem to activate anything as long as you clear his field. Plus you should always have 2 strong monsters on the field since all you need is 1 heal card.
