The target opponent chooses which card to exile as Grave Birthing resolves. |

You can cast Grave Birthing targeting an opponent with an empty graveyard. Even though that player won't exile a card from their graveyard, you'll still get an Eldrazi Scion and draw a card. |

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. |

A card with devoid is just colorless. It's not colorless and the colors of mana in its mana cost. |
| 8/25/2015 |
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. |

Devoid works in all zones, not just on the battlefield. |
| 8/25/2015 |
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. |

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

Eldrazi and Scion are each separate creature types. Anything that affects Eldrazi will affect these tokens, for example. |
| 8/25/2015 |
Sacrificing an Eldrazi Scion creature token to add  to your mana pool is a mana ability. It doesn't use the stack and can't be responded to. |

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. |
