Lethe, Soul Puppeteer

Indestructible
As long as your devotion to black is less than five,
Lethe isn't a creature.
At the beginning of your upkeep, you may
exile target creature card from a graveyard. If you
do, create a 2/2 black Spirit creature token with
flying.
{b}{b}{t}: Choose a creature card exiled with Lethe,
Soul Puppeteer. You may cast that card this turn.
"Her strings may be invisible, but she pulls on the very essence of your soul."
