5 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 2023Drawing cards from the bottom of your library is exactly the same as drawing from the top, except that you take the bottom card of your library and put it into your hand.
- 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.
- 13 October 2023River Song's first ability applies to all cards you draw while it is on the battlefield, not just the card you draw for your turn.
