Mafia: Get spy to tell fool who to visit, witch that person, and unless theres a docsave, you're guarenteed a double kill.

Town: Use GS to sanitytest cops on d1. Doc should keep protecting cop until doc dies, then watcher should go on cop. It'll sacrifice the cop, but will reveal the cop. BG should be careful who you visit in case you set off witch.

Fool: Just try to lay low, follow the spies advice, and aim for a maf/fool win on the last day.
