Swords of Concealing Light

Vanishing 2 (This permanent comes into play with
two time counters on it. At the beginning of your
upkeep, remove a time counter from it. When the last
is removed, sacrifice it.)
When Swords of Concealing Light enters the battlefield, turn all your opponents creatures
face down. Creatures your opponents control
come into play face down. Skip your opponents
combat phase, as long as you control Swords of Concealing Light.
