The Master, Gallifrey's End

Make Them Pay — Whenever a nontoken artifact creature you control dies, you may exile it. If you do, choose an opponent with the most life among your opponents. That player faces a villainous choice — They lose 4 life, or you create a token that's a copy of that card.

"A perfect army, right? Right? Oh, come in, my pretties!"

Doctor Who

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.

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.

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

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.

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.

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