Mmmm... Interesting, you balanced most of the moveset, but some new moves are kinda unbalanced.
Neutral air, it seems to be juts too spammable, combined with the extremely high recovery, its just seems too good.
Neutral b is also somewhat cheap, in ground. If you are facing an opponent without projectile, you can spam it untill you rack a lot of dmg.
Up b has way too much reach.
Chaos spear air moves you some distance to the side, its not much of a trouble, but kinda looks wrong.
Down b needs a bit more range, just a little, right now it has little use.
Other than those little details, you have balanced him pretty well.
BTW, isn't it time to change the poll?
