Khonshu, God of Night Traveler

Indestructible, Vigilance.
As long as your devotion to white is less than five, Khonshu isn't a creature.
When Khonshu enters the battlefield if it is
neither day nor night, it becomes day. As long as
it's night, all creatures you control get +1/+2.
{x}{t} - Khonshu and target creature you control
with converted mana cost X phases out.
