Innate: The passive looks much better, in regards to balance and effects. It may not be the most exciting, but surely it's a little less unoriginal. The two things I may point out is the name "Soul Carver" and the scalings. What is "Soul Carver" (I presume the first innate), and wouldn't you think a little more scaling for both the damage and AS buff be good? As in, there should be more levels for the damage (5/10/15/20/25/30), while the AS should be boosted a little, such as 40/50/60% instead of a flat 50%. I've nerfed a bit of the values for balance sake, but numbers are numbers; what is important is their intention not their values.

Q: It does seem like an ability better on a basic ability... but I see two issues with the current model:
 * The number of knives to the amount of possible damage makes rank 4 and 5 knives ult levels of damage. I recommend that you lower the scaling per rank less, and at the least raise the base knives to 2 so that at rank 1, such that you have 2/3/4/5/6 knives.
 * The damage shouldn't be flat throughout. By flat, I mean that each knife deals equal damage, as this causes the large damage the ability can deal, even if the damage doesn't scale anymore than 10 per rank. Consider the potential total damage that can be dealt. I would personally go for a XX (base damage) + (XX per knife) model, but it's best if you think for yourself how to alleviate this issue.
 * The number count of knives can be a detriment if each can proc on-hit effects and the likes. If you want the passive to proc multiple times, then limit each activation of Q to one proc of on-hit effects, but proc the innate as many times as the knives. If you want the innate to have more signification, this is even more of a reason to lower the damage on Q itself.

W: This ability is looking better than before. Not much to complain aside from needing a "%" at the end of the magic pen percentage.
 * I also wished to note that if you are granting champions % values, you should have their stat scalings do so too. It should not be (+20% AP), but (+1% per 5 AP) or the likes. If you meant flat increases, then say so (although I believe for the magic pen, flat is rather powerful, and you should research why yourself).

E: While better than damage immunity, becoming invisible in-combat is yet another problem. Champions that are capable of doing so has methods of being countered, but Levi can stealth, gain movement speed, dealing damage just passing by, all while ghosted. It's a bit of a cluster of passive effects... all while being unintuitive (below, I meant to say that E is alright but unintuitive).
 * Reflecting on this ability, I understand the thematic reason to having these effects, but this is what I mentioned about what you need to limit yourself from doing as a content creator: ideas that fulfill the characters theme but not their kit or balance.
 * This brings into mind that Levi is dangerously close, if not already the same, as the resident clown ... and even as you try to make differences, there are these similarities that are worrisome.

R: I personally am no good judge for pets, but I will only say that this ult only helps compensate for a dull effect, but does not creatively make a thematic purpose for Levi. You suggest that this is what Levi sends out upon those he hates... but this minion is emptier than any of the current ult-pets around, as we have no basis as to why he possesses this Feaster. may have contest, but his has a full story to explain who she is. I won't say remove it, but understand that the presence of this ult will make people wonder...
 * I don't understand what you mean by "endurance" but this is one hefty minion, with just a little less durability than other pets...

An AD mid laner with magic damage... I don't know if Levi fulfills that as much, as I do not play AD midlane much. However, if that is what you say is Levi's niche, it's a rather generalized one. He's a Marksman-Assassin (damage heavy, either in sustain or burst, who is supposed to be fragile?), but I don't see anything exciting in the kit from a description of "AD mid laner." I will cite how I am not the greatest critic for the best kits of all times; that's something to ask the likes of Primus, Empty and Lesdin. But if you do take a look at their kits, or some of my champs, they do more than fulfill a role and try to grab something more concrete. Plus, visually speaking, you should aim to add more zazz...
