This is pretty consistent in my opinion. How to use: Use Dimension Gate on Labyrinth Wall to dodge the equip spell that does damage every standby phase. Since your Labyrinth tWall has 0 attack, you won't care about his attack debuffs. Make sure to use Massivemorph at least twice on his strongest monster. There's a chance he uses his one trap card to negate one Massivemorph, and that's okay; you only need two. There's still a chance he goes above 3000, so Massivemorph is necessary. Use Storm to clear his field together with a field card (any). I added that field card because it's glossy and to remove possible spell cards that are annoying, it should clear his whole field. Use Enemy Controller on his monster (tribute Labrynth Wall to take the monster you buffed with two Massivemorphs), summon Vassal, use Secret Pass on it, Union Attack once, and attack. You could even add a Mooyan Curry to guarantee 8000+. I don't think you need to since there's a campaign going on. Just replace Yata-Garasu.
