Karametra, The Nuturer

Indestructible
As long as your devotion to green and white is
less than seven, Karametra isn't a creature.
Enchanted creatures you control have
"{t}: add one mana of any color to your
mana pool".
{2}{w}{g}: Reveal the top four cards of your library.
You may put a creature, land or enchantment
card from among them into your hand. Put the
rest into your graveyard.
