Freyr, the Prosperous God

Indestructible
As long as your devotion to white and green is less
than seven, Freyr isn't a creature.
When you cast a creature spell, if Freyr is a
creature, search your library for a basic land card
and put that card into your hand.
Freyr, the Prosperous God's power and
toughness are each equal to the amount of
land you control.
