A new ninja champ

So i was thinking what if riot made a champ like this:

Passive Whenever HE teleports behind an enemy champ ,monster,minion using Q or E, HE deals 10% of their max health(current health) dk whats best here

Q Has 3 Kunais.He can throw all 3 and he can teleport to them in the order wich he threw the kunais. It deals 60-200(+ 200% base ad). All the kunais last 1 minute.The teleport range is 1350 and if you hit a champion with Q He teleports behind him.

W A 2 or 3 hit passive.like a talon passive and if you combine w with his passive you do a lot burst.Deals 5%-15% max(current) health Again dk whats better here max or current health dmg.

E A small dash that at the end if he hits an enemy they get marked and HE can teleport behind them.The mark lasts for 8 seconds.

R He becomes untargetable and unstopable.HE becomes a ball of kunais after 2 seconds the ball of kunais explodes doing 200/400/600 (+150% gathered ad from items).After he explodes the kunais that didnt hit enemy champs,monsters act as Qs and you can teleport a maximum of 3 times with R.

I would really like for who reads this give opinion on if you like this champ,if you want to change his dmg numbers or Q E and R times and range.And i would really like if you could come up with a cool name for this champ. TY for reading.I really think this will be a high skill floor and high skill ceiling champ only bcs of his Q and R kunais bcs you nees to know where you placed your first second and third Q and where you R kunais are.
