Reveal mechanics proposed (meaning up for debate)
1. All flips will be revealed.
2. All lynches will be revealed. Night Kills will not be revealed, although, if players will pay close attention, that might not necessarily mean they will be uninformed.
Further experimental mechanics proposed - all of them involving potential shenanigans
1. Triad system (2-player vote/kill immunisation) Players will choose, during Night polls (there will be a Day 0 for this), between major and minor triads, in all their positions (inversions). According to their choice for a subsequent Day phase, every pitch's (player's) vote for his corresponding third or fifth will be worth 0 and, during the Night, the appointed (by the team) mafia member killer's attempt on his corresponding third or fifth will fail.
2. Axis system (1-player vote/kill immunisation) Players will choose, during Night polls (there will be a Day 0 for this), between primary (tritone), secondary 1 (lower minor third) and secondary 2 (upper minor third). According to the chosen relation, during the subsequent Day phase, each pitch's (player's) vote for his corresponding pitch (player) will be worth 0 and, during the Night, the appointed (by the team) mafia member killer's attempt on his corresponding pitch will fail.
3. Tone row, with designated pitch intervals (1-player vote/kill immunisation) Players will choose, during Night polls (there will be a Day 0 for this), between prime, retrograde, inversion and retrograde inversion forms (chosen forms will afterwards be taken off subsequent polls until a full rotation between the four forms is completed) , whilst also choosing a specific pitch interval (chosen intervals will afterwards be permanently eliminated from the subsequent polls). According to the chosen interval and row form, during the subsequent Day phase, each pitch's (player's) vote for his corresponding pitch (player) will be worth 0 and, during the Night, the appointed (by the team) mafia member killer's attempt on his corresponding pitch will fail.
