Pharika, Blight-Blessing

As long as your devotion to black and green is
less than seven, Pharika isn't a creature.
Indestructible.
Whenever you put a -1/-1 counter on a creature,
you create a 1/1 black and green snake
enchantment creature token with Wither.
{1}{b}{g}, Exile a creature from a graveyard: Put
a -1/-1 counter on target creature.
