- 20 September 2024Elk and Glimmer are both creature types. Enduring Vitality won't have those creature types when its last ability returns it to the battlefield because it won't be a creature.
- 20 September 2024A token that's a copy of Enduring Vitality won't return to the battlefield when its last ability resolves.
- 20 September 2024If a nontoken permanent that's a copy of Enduring Vitality dies while it's a creature, it will return to the battlefield as an enchantment when its last ability resolves. It won't have any card types other than enchantment.
