Once per game at night, can choose to switch roles with any player in the game.
The switched player will appear to themself as the same role with same day/night actions, but role will not work. Can still shoot guns, use crystals, etc.
If switched player was mafia, the mafia actions list is there, and they can still choose (but it will do nothing), but to the other members, the switched player isn't there and neither is their chat, but the doppelganger is put in their place. To the switched player, the doppelganger is not there. To the doppelganger, the switched player is in the mafia meeting.
Doppelganger is sided with the village (but can convert to mafia)
Doppelganger's visit converts to doppelganger (which is sided with the village)
ik this is a crazy-sounding role, but i am trying my best here.
