Overview
I believe this hero is still misunderstood as an atk speed built hero from pre revamp. Think of the lore. This hero is the strongest ninja and the villain to Hayabusa. They both need to apply stacks of marks but execute skill oppositely. Hayabusa multi-hits while Hanzo builts up for that juicy bite.
Strengths
Can dive and execute backline heroes. Can kill tanks who underestimate his lategame damage.
Weaknesses
Once you miss your 2nd skill and no stacks for your 1st skill, your ghost form can be easily killed. Be mindful of sneaky assasins and roamers hunting and waiting for you to return to you original body.
Bite & Kill
Magic boots for Ult & 1st skill cooldown. Sky Piercer for early snowball. Golden staff for instant stacks. Swap last items if you need Sea Halberd.
Movespeed is key especially in expanding rivers
Weakness finder for additional slow to your 2nd skill. Use Impure Rage instead for high hp enemy comp.
Battle Spell
Get Flame retri for that instant increase in hp-scaling damage during bite
