Rereading this and I still get chills. Bro just loved it so much he didn't care about what anyone thought or even if it was possible, 'why not just try?'
I find it more interesting that despite such a simplistic pattern no one has managed to realize this is how it works for so long. It's not like a crazy different pattern every time, just:
Attack 1 > 2 > 3 > Death Sword
Repeat until OOM
