ラニ

ラニが戦場に出るか攻撃するたび、これでないクリーチャー１体を対象とする。「ラニの印」という名前を持つ赤のオーラ・エンチャント・トークン１つをそれについた状態で生成する。そのトークンはエンチャント（クリーチャー）と「エンチャントしているクリーチャーは＋２/＋２の修整を受け、使嗾される。」を持つ。
使嗾されているクリーチャー１体が対戦相手１人に戦闘ダメージを与えるたび、調査を行う。

The Rani

Whenever The Rani enters or attacks, create a red Aura enchantment token named Mark of the Rani attached to another target creature. That token has enchant creature and "Enchanted creature gets +2/+2 and is goaded."
Whenever a goaded creature deals combat damage to one of your opponents, investigate.

Doctor Who

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.
