Obelisk of Reality

{3}: Untap Obelisk of Reality.
{8}, {t}: Obelisk of Reality doesn't untap during
your untap step. All permanents, spells, and
cards in all players' libraries lose all colors for as
long as long as Obelisk Of Reality remains tapped.
"It's as if this ancient structure had the ability to
drain the energy from the world around it."
