Mafia 100. Sylvan: Tree of Life.

Yashur, consider that neither role had any defense, and the city won because the elf moves first. Or they had 100% defenses that they broke that night, and the next day, Heroist executed them.

No. If there were no defenses, then Heroist probably wouldn't have executed the paladin, because he would have died from the elf with 100% certainty.
And if there were 100% defenses, then it's not a fact that they would have executed Heroist. :)
