If Nebka was confused today, then he is definitely not the Mafia.
Why would the Priest need to eliminate anyone? He might end up targeting the Warlord...
Here's a possible plan:
The House Elf isolates the Priest – this provides complete protection against both the Mafia and the Witch.
The Witch treats the Shaman with tea (which is fine, and also prevents him from being infected tonight).
While drinking tea, the Shaman simultaneously heals and cures one player – this provides a second layer of complete protection against the Mafia and the Witch.
The Knight goes to the Shaman – this is the third layer of complete protection (for the Shaman).
If the Herbalist doesn't get eliminated during the day, she can also heal/cure someone.
However, at the end of the night, we probably won't learn anything.
Therefore, it might make sense to have the Shaman protect the Priest, while the House Elf checks someone else.
Ideally, the Guardian shouldn't switch the person she's checking on, otherwise the results of the check will be useless.
