Enduring Courage
Enchantment Creature — Dog Glimmer
Whenever another creature you control enters, it gets +2/+0 and gains haste until end of turn.
When Enduring Courage dies, if it was a creature, return it to the battlefield under its owner's control. It's an enchantment. (It's not a creature.)

Rulings
Dog and Glimmer are both creature types. Enduring Courage won't have those creature types when its last ability returns it to the battlefield because it won't be a creature.

If a nontoken permanent that's a copy of Enduring Courage 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.
