Rulings

• 2015-08-25:

  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.

• 2015-08-25:

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

• 2015-08-25:

  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.

• 2015-08-25:

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

• 2015-08-25:

  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.

• 2015-08-25:

  Eldrazi Scions are similar to Eldrazi Spawn, seen in the Zendikar block. Note that Eldrazi Scions are 1/1, not 0/1.

• 2015-08-25:

  Eldrazi and Scion are each separate creature types. Anything that affects Eldrazi will affect these tokens, for example.

• 2015-08-25:

  Sacrificing an Eldrazi Scion creature token to add {C} to your mana pool is a mana ability. It doesn’t use the stack and can’t be responded to.

• 2015-08-25:

  Some instants and sorceries that create Eldrazi Scions require targets. If all targets for such a spell have become illegal by the time that spell tries to resolve, the spell won’t resolve and none of its effects will happen. You won’t get any Eldrazi Scions.
