Battle for Zendikar

Devoid (This card has no color.)
Exile target nonbasic land. Search its controller's graveyard, hand, and library for any number of cards with the same name as that land and exile them. Then that player shuffles his or her library.

Devoid works in all zones, not just on the battlefield.

A card with devoid is just colorless. It’s not colorless and the colors of mana in its mana cost.

Cards with devoid use frames that are variations of the transparent frame traditionally used for Eldrazi. The top part of the card features some color over a background based on the texture of the hedrons that once imprisoned the Eldrazi. This coloration is intended to aid deckbuilding and game play.

If a card loses devoid, it will still be colorless. This is because effects that change an object’s color (like the one created by devoid) are considered before the object loses devoid.

Other cards and abilities can give a card with devoid color. If that happens, it’s just the new color, not that color and colorless.

You may leave any cards with that name in the player’s graveyard, hand, or library. You don’t have to exile them.
