Kozilek's Monocrator

All {w}, {u}, {b}, {r} and {g} in the abilities and mana
costs of spells you control are replaced by {c}.
Spells you control have Devoid.
As long as your devotion to colorless is less than
ten, Kozilek's Monocrator isn't a creature.
(Each {c} in the mana costs of permanents you
control counts toward your devotion to colorless.)
