GOURDian Knot

Will of the Gourds - Starting with you, each player votes for trick or treat. If Trick gets more votes, each opponent sacrifices a creature and you gain control of those creatures, except they are zombies in addition to their other types. If Treat gets more votes, each opponent searches their library for a basic land and puts that land into play tapped, and you search your library for three basic lands and put those lands into play tapped.
