Hateful Eidolon
Enchantment Creature — Spirit
Lifelink
Whenever an enchanted creature dies, draw a card for each Aura you controlled that was attached to it.
From the echoes of a violent life, a terrible foe is born.

If an Aura you control is destroyed at the same time as the creature it enchants, Hateful Eidolon’s triggered ability counts that Aura to determine whether it triggers and how many cards you’ll draw.

If Hateful Eidolon dies at the same time as one or more enchanted creatures, its last ability triggers for each of those creatures. This includes Hateful Eidolon itself if it’s enchanted.
