I know he's possible, but when I realized he is always level 100, I realized how impractical beating him is. If you are good Zell can do 40,000-50,000 (lets say 40,000 because of mistakes and lower time limits) in one duel, Wishing Star can do 40,000 and homing laser can do 10,000. That is about the best you can do, which means if you are super lucky it goes like this W=wishing star, D=Duel, H=homing laser, A=acid and I=invincible moon.
A (he has vit 0 on) D W (80,000) (H D I H D W H D W) (does 270,000 each time) repeat 4 times. Ok, getting invincible moon 4 times in a row (I have had 3 times in a row once against him) is super unlikely in the first place, second Wishing star doesn't happen close to as often as I pictured, it would be more likely to require 6 or 7 invincible moons at least. It also is pretty hard to get 40,000 damage on average as well if you don't usually get 12 second duels.
But....I am still trying it anyways
