Shiki has enhanced physical abilities and can effectively see a target’s death which helps with predicting their next movements. It won’t help with Jaden though because she won’t be able to see his death ahead of time. Jaden won’t be losing this round. He has too many monsters, spells, and traps at his disposal for him to possibly lose this round. Jaden’s in prime position to secure a victory here and Shiki would need a stroke of luck to cause an upset. Jaden wins.
