Gravedigger

"“Can talk to dead members at night. May choose one person to revive, but will die in their place. Sided with the village.“"Note that if you revive a role with a limited ability (e.g. Sniper which can only shoot once, Bulletproof which only has one vest, Kamikaze, which can only explode once), they will receive their bullet/vest/bomb back.

1. Revive-Happy
The premise is very simple. You see a valuable role that isn't AFK, you revive it. This is the most used strategy by most players.

2. Passive
A lot of players take for granted one of the gravedigger's abilities: the ability to talk to the dead. Unlike the 1st strategy, you must revive only when absolutely necessary. Creepers may die and self-creeped, and you can tell his/her killer.

This strategy is not common because gravediggers have a chance of dying, losing the ability to revive, and important roles will get angry about it.

1. Wasted Kill
When reviving, try to do something like a "granny bait", luring mafias to kill you, so when you revive, the mafia's kill is wasted.

1. Day Communication
If you play in Android, you are able to talk at day.

If you are playing on IOS, you can stay in the graveyard chat and talk when day comes. However, once you go to the town hall chat, you can no longer access the graveyard chat until night.
