Der Zwölfte Doctor

Der erste Zauberspruch, den du pro Zug von irgendwoher außer aus deiner Hand wirkst, hat Demonstrieren. (Wenn du jenen Zauberspruch wirkst, kannst du ihn kopieren. Falls du dies tust, bestimme einen Gegner, der ihn ebenfalls kopiert. Eine Kopie eines Bleibende-Karte-Zauberspruchs wird zu einem Spielstein.)
Immer wenn du einen Zauberspruch kopierst, lege eine +1/+1-Marke auf Den Zwölften Doctor.

Le Douzième Docteur

Le premier sort que vous lancez depuis autre part que votre main à chaque tour a la démonstration. (Quand vous lancez ce sort, vous pouvez le copier. Si vous faites ainsi, choisissez un adversaire pour qu'il le copie aussi. Une copie d'un sort de permanent devient un jeton.)
À chaque fois que vous copiez un sort, mettez un marqueur +1/+1 sur Le Douzième Docteur.

12代目ドクター

各ターン内であなたがあなたの手札以外から唱える１つ目の呪文は実演を持つ。（あなたがその呪文を唱えたとき、これをコピーしてもよい。そうしたなら、対戦相手１人を選び、これをコピーさせる。パーマネント・呪文のコピーはトークンになる。）
あなたが呪文１つをコピーするたび、12代目ドクターの上に＋１/＋１カウンター１個を置く。

The Twelfth Doctor

The first spell you cast from anywhere other than your hand each turn has demonstrate. (When you cast that spell, you may copy it. If you do, choose an opponent to also copy it. A copy of a permanent spell becomes a token.)
Whenever you copy a spell, put a +1/+1 counter on The Twelfth Doctor.

Doctor Who

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

If any additional or alternative costs were paid to cast the spell with demonstrate, the copies will see those choices as well. For example, if the spell has a kicker ability and was kicked, the copies will also be kicked.

If the spell had an X value chosen for it as it was cast, the copies will have the same value of X.

If the spell requires targets, you choose the target of the original spell as you cast it. If you create a copy of the spell, you may choose new targets for the copy as you create that copy. Similarly, the opponent you chose to create a copy may choose new targets for that copy as it's created. In other words, your opponent will know the targets of your original spell and your copy when choosing the new targets, if any, for their copy.

If the spell with demonstrate had any modes chosen for it as it was cast, the copies will have the same modes chosen for it.

If you cast the spell and choose not to copy it, no opponent will get to copy it either.

If you copy a spell with demonstrate, you then immediately choose an opponent. If they copy the spell, it goes on top of the stack.

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.

This means that if you cast a spell with demonstrate and both you and an opponent copy it, the opponent's copy will resolve first, then your copy will resolve, and finally the original spell will resolve.

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.

You choose whether to make a copy as the demonstrate ability resolves. This happens before the original spell resolves. Your copy goes on the stack above the original spell.
