SMTV: Vengeance, Faster Shiva Boss Battle | i3 2120/4GB RAM/GT 1030

Real life has been getting in the way so I haven't been able to play SMTVV as much as I'd like.
Nonetheless, I reached the endgame in my 2nd playthrough/cycle, and I decided to record my latest fight with Shiva making use of a very simple yet very broken strategy involving a few Magatsuhi Skills.
I wanted to stack 2 or 3 Luster Candies, but I got very tired of Kali and Ganesha constantly undoing most of their effects by using Matarunda and Masukunda on my party, so I said "Fuck it" and unleashed Murakumo.

Explanation:
I destroyed Shiva by using Murakumo, the strongest Strength-based Almighty skill for the protagonist, about 23 or 24 times.
-Omnipotent Succession lets you repeat the next offensive skill used 3 times after its original cast.
-Evergreen Dance recharges a chunk of the Magatsuhi Bar which is used to cast Magatsuhi Skills.
-Omagatoki: Charge lets you retain charge effects (like Omnipotent Succession's) until the end of the turn.
Combine these with some buffs and debuffs, and you can obliterate the huge majority of enemies in the game.
It probably won't work as well on the other superbosses, but I'm sure as hell going to try regardless.
