Angel of Sanctions

• WOTC Official Reminder Textofficial rules
  Embalm — Embalm [cost] ([cost], Exile this card from your graveyard: Create a token that's a copy of it, except it's a white Zombie [type] with no mana cost. Embalm only as a sorcery.)

• WWizards of the Coast2017-04-18
  Official Ruling
  The token copies exactly what was printed on the original card and nothing else. It doesn't copy any information about the object the card was before it was put into your graveyard.
• WWizards of the Coast2017-04-18
  Official Ruling
  The exiled card returns to the battlefield immediately after Angel of Sanctions leaves the battlefield. Nothing happens between the two events, including state-based actions.
• WWizards of the Coast2017-04-18
  Official Ruling
  If a token is exiled this way, it will cease to exist and won't return to the battlefield.
• WWizards of the Coast2017-04-18
  Official Ruling
  Auras attached to the exiled permanent will be put into their owners' graveyards. Any Equipment will become unattached and remain on the battlefield. Any counters on the exiled permanent will cease to exist.
• WWizards of the Coast2017-04-18
  Official Ruling
  In a multiplayer game, if Angel of Sanctions's owner leaves the game, the exiled card will return to the battlefield. Because the one-shot effect that returns the card isn't an ability that goes on the stack, it won't cease to exist along with the leaving player's spells and abilities on the stack.
• WWizards of the Coast2017-04-18
  Official Ruling
  If the card copied by the token had any "when [this permanent] enters the battlefield" abilities, then the token also has those abilities and will trigger them when it's created. Similarly, any "as [this permanent] enters the battlefield" or "[this permanent] enters the battlefield with" abilities that the token has copied will also work.
• WWizards of the Coast2017-04-18
  Official Ruling
  If Angel of Sanctions leaves the battlefield before its triggered ability resolves, the target permanent won't be exiled.
• WWizards of the Coast2017-04-18
  Official Ruling
  The token is a Zombie in addition to its other types and is white instead of its other colors. It has no mana cost, and thus its mana value is 0. These are copiable values of the token that other effects may copy.
• WWizards of the Coast2017-04-18
  Official Ruling
  For each card with embalm, a corresponding game play supplement token can be found in some Amonkhet booster packs. These supplements are not required to play with cards with embalm; you can use the same items to represent an embalmed token as you would any other token.
• WWizards of the Coast2017-07-14
  Official Ruling
  Once you've activated an embalm ability, the card is immediately exiled. Opponents can't try to stop the ability by exiling the card with an effect such as that of Crook of Condemnation.
• WWizards of the Coast2017-07-14
  Official Ruling
  If a spell or ability puts a creature card with embalm into your graveyard during your main phase, you'll have priority immediately after that spell or ability resolves. You can activate the creature card's embalm ability before any player can exile it with an effect, such as that of Crook of Condemnation, if it's legal for you to do so.
