Mafia 106. Plague. Dragon Utopia

They should try to execute him during the day and infect the town at night.

If the Plague is executed during the day, the Mafia won't be able to infect anyone anymore. So, I would try not to execute the Mafia member during the day and instead save him.
And considering that it's quite easy to get into a situation in the game with a Gunslinger (or rather, with two Gunslingers, one of whom only kills Mafia members, which means he doesn't have to worry about making a mistake) and a Doctor, where only Shabnak is left of the Mafia, I would advise the Mafia to save the Doctor even if the Prophet and Albino are still alive.
This leads to the question: isn't it too much to give the Doctor such forced support from the Mafia, in addition to all his other advantages?

Also, the Mafia should think before stealing the ultimate ability, as the Imposter's hypnosis is displayed in the newspaper along with the target's nickname.

So what? There are two redirection abilities in the game besides Take Control. Well, it will show that hypnosis was used on player X, so what?

The effectiveness of the Plague's actions is somewhat overestimated - until the third night, there are 5 roles for whom infection doesn't matter, then 4, but Clara will be able to heal and cure the Commander, as she will be with him.

This is all you need to know about Shabnak's effectiveness. Also, the fact that you can't eliminate the second Gunslinger (!!) (who is also Clara) if the Mafia wants to get at least some benefit from Shabnak's night kill.
