Der Vierte Doctor

Du kannst dir zu jedem Zeitpunkt die oberste Karte deiner Bibliothek anschauen.
Möchtest du ein …? — Einmal pro Zug kannst du oben von deiner Bibliothek ein historisches Land spielen oder einen historischen Zauberspruch wirken. Wenn du dies tust, erzeuge einen Speise-Spielstein. (Legenden, Artefakte und Sagen sind historisch.)

Le Quatrième Docteur

Vous pouvez regarder la carte du dessus de votre bibliothèque à tout moment.
Vous voulez un... ? — Une fois par tour, vous pouvez jouer un terrain historique ou lancer un sort historique depuis le dessus de votre bibliothèque. Quand vous faites ainsi, créez un jeton Nourriture. (Les artefacts, les légendaires et les sagas sont historiques.)

４代目ドクター

いつでも、あなたはあなたのライブラリーの一番上にあるカード１枚を見てよい。
……いかがかな？ ― 毎ターン１回、あなたはあなたのライブラリーの一番上から、歴史的な土地１つをプレイするか、歴史的な呪文１つを唱えるかしてもよい。そうしたとき、食物・トークン１つを生成する。（歴史的とは、アーティファクトや伝説や英雄譚のことである。）

The Fourth Doctor

You may look at the top card of your library any time.
Would You Like A...? — Once each turn, you may play a historic land or cast a historic spell from the top of your library. When you do, create a Food token. (Artifacts, legendaries, and Sagas are historic.)

Doctor Who

Essentially, The Fourth Doctor lets you play with the top card of your library revealed only to you. Knowing what that card is becomes part of the information you have access to, just like you can look at the cards in your hand. You may look at the top card of your library whenever you want, even if you don't have priority. This action doesn't use the stack.

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

If the top card of your library changes during the process of casting a spell or activating an ability, you can't look at the new top card until the process of casting the spell or activating the ability ends (all targets are chosen, all costs are paid, and so on).

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.

Food is an artifact type. Even though it appears on some creatures, it's never a creature type.

Whatever you do, don't eat the delicious cards.

You can't sacrifice a Food to pay multiple costs. For example, you can't sacrifice a Food token to activate its own ability and also to activate Maraleaf Rider's ability.
