Ok, so having a fairly positive feedback for these in general discussion i wanted to suggest these 2 ninjas, Sasuke (Final Valley) and Naruto (Final Valley)

For Sasuke i would make an irremovable ignition chase that would be Honoikazuchi, amenotejikara passive where he would make an opponent hit himself with his own spell using his rinnegan. Indra's arrow for a mystery, high chance of dodging standard attacks by using shinra tensei, and im sure they would be able to finish him off from that point.

Regarding Naruto, I dont really know his abilities to the fullest so im just gonna leave it to the devs to finish him off.
