Chocolate and Vanilla Swirl

Destroy all nonblack and nonwhite permanents
If any plains or swamps are destroyed, return
each of them to each original owner and that
land may produce an extra mana of the same
type the first time it's next tapped for mana
"Either you're chocolate, you're vanilla, or
you're butterscotch. You can't be all three."
Bruno Mars, Dark Magician
