Hi.

I think it would be a cool idea if you add the deidara from this fight as he used some cool ninjutsu and i think a lot of people would be interested in getting him as well. As his standard he could spawn those clay monsters and his mystery could be the c0 explosion which is his ultimate art. This is a fun ninja idea that i like and he would also bring in a lot of attention in my opinion. As one of his passives he could have massive ninjutsu growth so his art dont go to waste.
