Cast out the Gods

This card can only be cast if there are three or
more gods on the battlefield.
Return all gods to the bottom of their owners
library. If that god was a commander it cannot
be placed into the command zone this turn.
With one little lie Karag's rage was sparked. In his
anger all of his children were then cast down into the
mortal realm far weaker then they once were.
-Wanderer Athus, Scholar of the Gods
