Alright then. Let's see...
Piplup - Vigi who'll die if the kill fails + Roleblocker (of sorts)
Drac - JOAT (Watcher who watches someone who voted Drac)
Nick - Tracker + Motion Sensor
Morda - Public ability reveal + Day Ability check
Mera - Doctor who saves the last person he votes + "Limited visit blocker" (of sorts)
Cel - Mason + "I will know everything about you if I predict you getting lynched"
Zone - 30% Roleblocker if visited + "Lynch savior" (of sorts)
NP - Mason + "Lose your abilities if you lynch me"
Naga - "Messager" + Redirector
TI, TP, TS(?), TS, ???, TS(?)
Uh... I don't even know what category NP is --and there is probably another type of system in the official MU Dictionary.
The first point is: If scum work "normally" (i.e. predictably), then we are certain who they will target: Mera and Nick, because they are TI and TP. However this is under the assumption that Mera doesn't lie about his ability, and is actually a TP. If he is legit TP, then Nick should be safe and check whoever he finds suspicious.
Next up is Cel: I don't see any reason why Piplup's ability would last permanently, so you should get that ability back Tonight. I dunno who he will target, but I am betting even more 50 nuffies that it will be either me or NP.
NP is basically not doing anything, so unless Nick wants to check him "for good measure" (something which I don't recommend), he is basically extra luggage. I also want to say something else about him, but if I do so then NP will definitely either be 100% killed or 100% scum.
Then comes Naga: This is the interesting part: If Naga can redirect NP to me, and I die, then this basically blocks the possibility that NP is the N2 killer, whether he is scum or not. Basically if I die tonight, then we got ourselves a scum! Then there is also the message thingy... Dunno what to do with those.
As for me: I have the chance to save someone tomorrow from getting lynched... Well, then it's obviously someone towny, probably either Nick or NP. As for my passive: The worst that can happen is if Naga actually redirects NP to me and I die... then --I wouldn't be surprised if that were to happen.
Still, the actions that Naga does are all IFs in the end. It is also possible that he doesn't use his ability this Night, as to not mess up town.
