Ariel, the swordsman

I'd like to recommend a hero whose name might be Ariel, the Night Killer.

Ariel could be a swordsman. His Passive could be a big forward thrust on every 3rd strike that could penetrate as many as 3 enemies if they are close enough. His Q could be a backward somersault ending in a backward strike. His W could be duplicating himself and making a forward oblique thrust (ie. Ariel and his double would make an X-shaped movement during the thrust). His E could be the same as Yasuo's E but Ariel could use two blades and make a full turn as he moves forward. His Ultimate ability could be quarduplicating himself, jumping in the air and coming down with a vertical blow on an enemy (after pressing R and selecting an enemy). The passive of his Ultimate ability would be taking 3% of the opponent's armor.

I'd very much like to have your feedback.
