3 rulings from Wizards of the Coast
- 10 November 2020The ability that defines Revenant's power and toughness applies in all zones, not just the battlefield.
- 10 November 2020If Revenant is dealt lethal damage at the same time as another creature you control, both die at the same time. The other creature won't die in time to raise Revenant's toughness.
- 10 November 2020As long as Revenant is in your graveyard, its ability will count itself.
