Ultaris, God of Conspiracy

Indestructible
As long as your devotion to blue and black is less
than seven, Ultaris isn't a creature.
{2}{u}{b}, {t}: Each opponent mills the top two
cards of their library. Until the beginning of your
next end step, if a noncreature spell was milled
this way, you may cast it from its owners
graveyard by paying life equal to its converted
mana cost.
