  Official Ruling
  The player who controls a face-down permanent may look at it at any time. Notably, if the cards were put on the battlefield face down from another player's library, the player that owns them does not get to look at those cards.

  Official Ruling
  A player facing a villainous choice can always choose either option, even if one or both of the options are impossible. For example, if one of the options is to sacrifice a creature, a player who controls no creatures can still choose that option.

  Official Ruling
  Unlike other creature types in Magic that are each only one word, the two words "Time Lord" represent a single creature subtype. Time Lord is the only two-word creature type.

  Official Ruling
  If, for any reason, the face-down creature is turned face up, the effect making it a Cyberman ends. It will be whatever is printed on the card.
• WWizards of the Coast2023-10-13
  Official Ruling
  If a spell or ability requires multiple players to face a villainous choice, the result is a little different from other effects in Magic. In that case, the first player in turn order makes their choice and the action for that choice is performed before the next player makes their choice. Then each of the remaining players repeat this process in turn order.

  Official Ruling
  Neither "Time" nor "Lord" are creature types. Some older cards were printed with the subtype "Lord," but all of those cards have updated Oracle card text that removed that type.

  Official Ruling
  Each creature turned face down this way or put onto the battlefield this way is a 2/2 Cyberman artifact creature with no name and no color.

  Official Ruling
  If an effect instructs you to choose a creature type, you may choose Time Lord.

  Official Ruling
  Double-faced permanents that are already on the battlefield can't be turned face down this way. However, a double-faced card can be put onto the battlefield face down from another zone this way.

  Official Ruling
  When a player faces a villainous choice, they first choose one of the two options, then all actions in the chosen option are performed.
