Mt. Devil Divider boom. That's what I'm calling it for lack of better explanation.
This will obviously work better with more attacks... I think.
This is what you do. Spend eternity (or about 3 turns which seems like an eternity in this meta) controlling with Valued but not Trusted, Undisputed Ruler and Ka Technique, reducing damage with Sa when blocking is not an option. Speaking of which, cards without a block not named Valued but not Trusted, Berserker Rage or Undisputed ruler are at 3 copies to minimize the chances of a blockless hand.
Mt. Devil Divider -> Yoshimitsu E on it (lose 5) -> Berserker Rage x as many as you have (lose 3X for +5X) -> G-Corp + IP/UW (lose 2 for G-Corp, +5 damage for UW) -> Brooding (lose 1, +1) -> In Search of Plunder (lose 2, +2)-> (Heir to the Storm first E (destroy one for +2 or so) -> Heir to the Storm second E (destroy for + [5+5X+2+5+1+2+2?) x as many as you have -> Yoshimitsu character E -> deals damage, Yoshimitsu character R
Is that even game at this point? Math fails me somewhat.
