His current problems

-His raw mystery is too dull because Bond Mystery exists.

-Chase is a must for power stack due to its synergy with passive.

-Power stack can be interrupted with consistent Paralysis, crowd controls like Immobile/Dream or chase dodges.

Aim of my suggestions:

-Toned up raw mystery

-Additional power stacks

-Power stack consistency

-''Yellow Flash of Konoha''
