Visions of Desolation

Sacrifice X non-token permanents.
For each opponent, destroy up to X target non-basic lands they control. Search all player's hand, library and graveyard and exile all cards with the same name as any land put into exile or a graveyard this turn, then shuffle each library.
"Walking the Dreamlands I have glimpsed upon unfathomable powers. We are but dust in the wind."
