You can farm him with elements unite, either by summoning GG or not.
Only summon GG if he has three face up cards on the field that are not time wizard. This doesn't happen all the time, however.
Option 2, is if he has two face up monsters and one face down, you can just keep the three guardians on the field, but I recommend putting kazejin in defense as his thousand dragon + graceful dice could damage you over 500hp. Always keep Sanga and Suijin in attack. I highly recommend THTD as a fusion because it thins your deck and can provide enough points if you're using the non Union attack method. I can get 7000-8000 every time. I just use my basic farming deck, but you should be able to customize to your preferences.
He won't use Time wizard on the three guardians, oddly enough. I'm guessing the AI knows they can't attack, because Joey kept his monsters in attack until I summoned THTD. Riryoku + martyr is enough to get a direct piranha attack over 9999
Maybe I should have been more patient, but pretty soon, I'm not going to have as much time for this game as I would like, and I saw the ticket as a chance to focus on other duelists and events. And it doesn't help that the ranks are going to reset before I have a chance to work up to better rewards. Also, I am not a dude.
