Choius, God of Nyx

Indestructible
As long as your devotion to colorless is less than 5, Choius isn't a creature. (Each {1} in the mana cost of permanents you control counts towards your devotion to colorless.)
Whenever another enchantment enters the battlefield, put a +1/+1 counter on Choius.
Other enchantment creatures you control get +1/+1.
