3 rulings from Wizards of the Coast
- 13 October 2023Unlike 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.
- 13 October 2023If an effect instructs you to choose a creature type, you may choose Time Lord.
- 13 October 2023Neither "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.
