Persephone, Goddess of Spring

Indestructible
As long as your devotion to black and green
is less than seven, Persephone isn't a creature.
Whenever a land enters the battlefield under
your control, exile target card from a graveyard.
If it was a land card, add {b} or {g}. Otherwise, its
owner creates a 1/1 green Dryad enchantment creature token with deathtouch.
