Vhioraxr, Unraveler of Sanity

Indestructible
As long as your devotion to blue and black is less
than seven, Vhioraxr isn't a creature.
At the beginning of each opponent's upkeep, exile
target nonland permanent that player controls
chosen at random with X time counters on it,
where X is its converted mana cost. It gains
suspend if it doesn't have it.
