He can end up one against one with a Mafia member. And here, randomness will essentially determine the winner.

Such an outcome is unlikely, but the Mafia should blame themselves for not taking care of Oyun in time.

Or two against two Mafia members.

Yeah, Clara against Shabnak and the Prophet.

Since Oyun is "easily defeated" and so on, here are two options:
1. 100% doubling, but every 2 turns.
2. 100% doubling every turn (in case of a block or using an ultimate, the vote remains one).

In my opinion, both options only unnecessarily complicate things for the Mafia. Yashur, it seems like you are simply trying to prevent any manifestation of randomness in the game, even if it is unlikely to affect anything
I don't want to remove the percentages from Oyun because it's a characteristic of the character, not a particularly pleasant one, but still.

Until the third day (1st, 2nd, and 3rd night, 1st, 2nd, and 3rd day), he cannot be killed or hanged. From the 4th night, he has one protection against being killed.

It's not until the third day, but until the fourth :o
Why so long? It will be awkward to have the ability to execute only Mafia members for three days in a row, while the main threat is unattainable. They can help against the Mana, especially if the trio dies. Although I agree about the invulnerability until the fourth night.

If one of them (Bachelor, Haruspex, Commander) kills someone personally, they receive a one-time protection against being killed in addition to their immunities. (the second protection will not accumulate until the first is used, the protection saves from one kill, but will not help in case of a double shot)

This is unnecessary in my opinion. I think it's better if he simply has 2 protections from the 4th night, otherwise Albino can immediately kill him.

And yes, protection against execution for each world that leaves the trio, regardless of the reason for leaving.

Then let Clara be included in the "trio" instead of the Commander. If the vulnerability to being killed depends on the time, rather than the death of key roles, the Mana will try by all means to feed on them, but otherwise, he can get a maximum of 2. He cannot kill Clara, and it will be difficult for the Mafia to do this by accident, considering that the Commander will protect her, and they themselves will not do such a favor to the Mana. And hanging Clara - well, what can you do, it's a terrible failure of the city, just like with the Commander in the original version.
