Enchantment Creature — Otter Glimmer

Oracle Text

Double team\nWhenever you cast an instant or sorcery spell, creatures you control that are Otters and/or enchantments get +1/+1 until end of turn.\nWhen Enduring Friendship 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.)
