My strategy was pretty simple, since I knew myself and the fact that I would rationally not make any over defensive moves like making more essence swords since my opponent was doing the same as I would just wait till their lower level technique tired them out, I decided to use this to my advantage.
The clone didn't seem to be capable of complicated thinking anyway and 'Omni-viewing Eye' was also disabled so it couldn't sense me activating the technique sequence before it was too late, and it likewise couldn't evade five different sword, as a result my hit was bound to claim its life.
However, such an accomplishment was at the cost of me losing my life, well, my virtual life at least.
