Oh wow, that's a lot more than just a little scumsided.
The normalcy is debatable here. I don't think your Day Vigilante Revealer needs the "Revealer" in the name; it's a common variant of Day Vigilante (one in which you have to make the post in-thread, which automatically reveals you as being responsible for the kill). The thing is, Day is not a whitelisted modifier, and as such it needs to be approved by the NRG as being within the "spirit of Normals" to be able to be run.
I should note that this discussion has come up before. Some members of the NRG are very much in favour of Day Vigilante (specifically) being permitted as a Normal role. Others, however, are against, and that includes me; especially as I'm one of the reviewers here, I'm one of the people you (and/or the other reviewers) will have to convince if you want to be able to run the role. I personally think that the role should be confined to Theme games, and doesn't have much of a place in a Normal. Part of the problem is that the mere possibility of a dayvig in a setup has a tendency to lead to annoying gambits day 1, and so is something that will potentially affect any Normal game, not just yours (if the role gets approved, I imagine people will try dayvig gambits in a lot more Normals). Part of the problem is that it interferes with the normal day/night cycle, which is something that Normals aren't supposed to do.
I have no other normalcy concerns; you seem to have no problem understanding action resolution or role wording. There are a few things missing from your ruleset that players would expect. One is deadline lengths, and what happens at deadline (I'd very much recommend "no lynch at deadline"). The other is voting/hammer rules; these work the same way in basically every Normal/Open on mafiascum.net, and thus experienced players can probably guess, but it's far from unheard of for a newbie to decide to play a Mini Normal as their first game, so it helps to explain it just in case someone's never seen them before. (You might also want to hyperlink the
site rules; one thing I've discovered reviewing Normals is that many people, even those who meet Normal modding requirements, don't actually know where they are, and a link will help those people out.)
In terms of balance, the dayvig approximately cancels out the "missing" town member (this being 9:3 rather than the more usual 10:3), whilst confirming itself as town. So when determining balance, this setup can be considered much as a 10:3 with Innocent Child + Doctor + Motion Detector + 7 VT versus Roleblocker + Neapolitan + Encryptor. The thing is, that setup would be scumsided even if the scumteam were all Goons; Town simply don't have enough power to balance a 10:3 (or the corresponding 9:3). The Motion Detector is actually fairly strong for a Motion Detector in the setup, being able to detect two of the scum (and even the third if they target the Encryptor), but the problem is that a "motion" result is very weak as guilties go (it's trivially explainable away by the scum in question and can happen completely innocently to a VT), and a "no motion" result can still happen even to scum. (Note that a 1-shot nightvig is almost as strong as a 1-shot dayvig, and the presence of a Doctor makes the two roles even closer in power for reasons related to no-lynching at mylo, so until the normalcy's decided we can try to balance the setup around a 1-shot vig without having to worry about exactly what sort of vig it is.)
Given the amount of scum power we have here, I'd say that to balance this, town needs two power roles in place of the Motion Detector and one VT, each of which is by itself likely to gain information worth around the equivalent of 1 Cop investigation over the course of the game, taking into account the possibility that it dies or gets permanently blocked before any results can come out, and with the assumption that town roles can't confirm themselves purely with their claim (given the existence of a scum Neapolitan, it's very unlikely that town can confirm themselves in this way, as there are too many possibilities for which roles go on which teams). (You can't really balance the game without adding a power role because scum has both the ability to lock down the Motion Detector slot forever, and enough information to conclude that that's the correct strategy; with a Roleblocker on their team, a scumteam aware of theory should be looking for an investigative role that they can permalockdown, as permablocking ability is most commonly provided to the scum as a counter for an investigative role that would otherwise break the game for town if unchecked.) We can assume that in this setup, powerful investigative roles aren't going to live beyond day 4 or maybe 5 at the most before they get killed, permalocked by the scum, or disregarded because there's no time left to verify their claims (claiming a guilty on someone isn't exactly very convincing at lylo, because scum often do it in order to attempt to close out the game and try to "get in first" against a possible town claim). As such, the first change I'd like to recommend is to
replace the Motion Detector with a Follower
; it's a very similar role (both in terms of what it does and how often it's used), but substantially more powerful (because it gets a fairly reliable guilty on the scum who makes the kill).
This change isn't enough by itself; you'd want to add another town power role, and ideally one that doesn't care which scum makes the kill (because otherwise you run into the effect in which town's roles tend to be better late and thus town gets major advantages from lynching scum early compared to late and scum gets major advantages from identifying town PRs early compared to late, thus small early advantages tend to snowball, causing huge amounts of swing). The most obvious change that comes to mind for me here is to
add a 1-shot Gunsmith for town
; this setup looks pretty much tailor-made for it, as it naturally has a false-positive role (the Vigilante; this works rather better with a nightvig as a dayvig is as unlikely to be Gunsmithed as a Miller is to be Copped), and two other potentially Gunsmith-interactive roles elsewhere (the town Doctor, and the mafia Neapolitan who could be replaced by the equivalent Vanilla Cop). You might want to think about whether to give scum a Neapolitan or a Vanilla Cop; the two roles are identical in every way for scum even if you add a Gunsmith, but giving scum one or the other might influence what they claim. (In particular, scum might not realise that Vanilla Cop is an excellent Neapolitan fakeclaim for escaping a Gunsmith guilty, so this basically comes down to whether you want to support scum who aren't 100% brushed up on their theory or whether you want to punish scum who don't have all the theory worked out; this is basically a moderation style issue. Note that as you have an Encryptor, scum may be able to coach each other on the relevant theory if the situation comes up.)
My suggestions aren't the only way you could balance the setup; rather, they're one particular path you could take the setup down. If you have your own suggestions for balancing the setup, or other ideas about what you'd like to see, we can try to work with those instead, and most likely the other reviewers will have their own idea about how to balance the setup. (I think it's likely that someone will suggest reducing the amount of scum power; I considered this but it doesn't really seem to help balancing the setup based on the way that the other roles work out. Adding town power seemed to work better.)
