Enduring Innocence (Duskmourn: House of Horror)

Enchantment Creature — Sheep Glimmer - Lifelink
Whenever one or more other creatures you control with power 2 or less enter, draw a card. This ability triggers only once each turn.
When Enduring Innocence 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.)
