First: After reviewing the events at the end of yesterday, one thing stood out - as it turns out, I misread the vote count, and neko, not Gorckat, was the leader on the Sikario lynch. This elevates neko to "all-but-confirmed town" in my eyes, and drops Gorckat down to "likely town" along with whichever one of Pra and Arakorn I'm not lying about due to mason-ness.
Now: To follow up on my original plan, I think I found something that should remove the last vulnerability in the plan.
In addition to his Rocket of Death, Soupfly has claimed a horn-like object. I (like Soupfly himself) think that this item is likely a roleblock. If this is, in fact, the case, then we are all-but-guaranteed a town win, because in the current situation a roleblock is as good as an investigation.
Assume that we lynch MBF as town, Soupfly successfully vigs Gorgon as town, and I am NK'ed as town (obviously). Town lynches Javert as town, and then Soupfly uses his third ability to attempt to attempt to roleblock whichever one of {Pra, Arakorn} is not the second mason.
If the third item works as expected and there is a kill, then a town win is guaranteed because Soupfly's target is confirmed town (since said target couldn't have made the mafia kill), leaving 3 out of 4 players all-but-confirmed (assuming that Soupfly is killed N4, then my mason partner, Soupfly's N3 target, and neko) and we lynch scum FTW. (D3 lynch MBF, N3 Tar mafia killed, N3 Gorgon vigged, D4 mason claims (clearing another player), D4 Javert lynched, N4 {Pra, Arakorn} RB'ed, N4 Soupfly mafia killed, D5 lynch Gorckat ftw (Arakorn, Pra, neko clear) - note that this scenario
assumes
optimal play by the scum)
If there is no NK on N4, then town enters D5 with 5 alive (Arakorn, Pra, Soupfly, neko, gorckat). Lynch whichever of {Arakorn, Pra} was RB'ed; if that fails, lynch Gorckat ftw.
If Soupfly is killed tonight instead of me and I get another innocent, then we have 4 of 6 living players all-but-confirmed town (me, Javert, neko, mason partner) and win the game in 2 lynches.
Of course, if one of {MBF, Gorgon, Javert} is the last scum, then the game ends early with a town victory.
If we are correct in believing that Soupfly's noise maker is a roleblock, then the only way that the Mafia have any chance of winning is if one of Gorckat, Pra, or Arakorn is a Mafia Roleblocker (and even then we have a 50% chance of winning based on random chance alone) or if we are dealing with a second mafia (unlikely given known information). If Soupfly's third ability does not RB and we reach LyLo, then we have a 50% chance of winning even if we flip a coin (neko + mason partner clear, Gorckat and one of {Pra, Arakorn} uncleared - and even in the worst case scenario [Soupfly inadvertently motivates scum] we have a 3 player endgame with 1 player cleared)
Acceptable changes to the plan: lynching Gorgon today and killing MBF tonight, placing Gorckat ahead of {Pra, Arakorn} in the lynch order (and therefore having Soupfly block Gorckat N4).
