Sauron, the Necromancer (The Lord of the Rings: Tales of Middle-earth)

Legendary Creature — Avatar Horror - Menace
Whenever Sauron attacks, exile target creature card from your graveyard. Create a tapped and attacking token that's a copy of that card, except it's a 3/3 black Wraith with menace. At the beginning of the next end step, exile that token unless Sauron is your Ring-bearer.
