永劫の勇気

あなたがコントロールしていてこれでないクリーチャー１体が戦場に出るたび、ターン終了時まで、それは＋２/＋０の修整を受け速攻を得る。
永劫の勇気が死亡したとき、これがクリーチャーであった場合、これをオーナーのコントロール下で戦場に戻す。これはエンチャントである。（これはクリーチャーではない。）

Enduring Courage

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.)

A token that's a copy of Enduring Courage won't return to the battlefield when its last ability resolves.

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.
