Flash, vigilance
As long as your devotion to white and blue is less than seven, Anubis isn't a creature.

"Let the eternal darkness embrace you."

As long as your devotion to white, blue, and black is less than seven, Anubis isn't a creature.
Nightcrawler - When Anubis enters the battlefield, if black mana was spent to cast this creature, detain a target creature.

Nightcrawler is a made up Ability Word, by yours truly. The generic text is: "When X enters the battlefield, if a 3rd mana color was spent to cast X, do Y." Y will typically be something associated with the mana colors actually in the mana cost. Also, the 3rd mana color will typically be involved in the devotion, if the creature has an ability the revolves around devotion, like gods do.[/spoiler]

There's the only fix I could find. That said, I really don't understand the word choice of "nightcrawler" as it relates to the flavor of the card. The interaction with devotion is weird, too, considering there hasn't been a card yet which uses devotion of a color that it isn't. Finally, detaining a creature for only one turn is weak. (Remember, detain only lasts until your next turn.) I'd ditch the weird black mana requirement and do this card something like this:

Anubis, Lord of Mummification {3}{w}{u}
Legendary Enchantment Creature - God
