Peri Brown

Der erste historische Zauberspruch, den du pro Zug wirkst, hat Einberufen. (Deine Kreaturen können dir helfen, ihn zu wirken. Mit jeder Kreatur, die du tappst, während du ihn wirkst, bezahlst du für {1} oder ein Mana der Farbe jener Kreatur.)
Begleiter des Doctors (Du kannst zwei Kommandeure haben, falls der andere der Doctor ist.)

« Je m'appelle Perpugilliam Brown et je peux crier aussi fort que vous ! »

Le premier sort historique que vous lancez à chaque tour a la convocation. (Vos créatures peuvent aider à le lancer. Chaque créature que vous engagez en le lançant paie {1} ou un mana de la couleur de cette créature.)
Compagnon du Docteur (Vous pouvez avoir deux commandants si l'autre est le Docteur.)

「私はパーピュギリアム・ブラウンよ。声の大きさならあなたに負けない！」

ペリ・ブラウン

各ターン内であなたが唱える１つ目の歴史的な呪文は召集を持つ。（あなたのクリーチャーが、その呪文を唱える助けとなる。それを唱える段階であなたがタップした各クリーチャーは、{1}かそのクリーチャーの色のマナ１点を支払う。）
ドクターのコンパニオン（もう一方がドクターであるなら、あなたは統率者２体を使用できる。）

The first historic spell you cast each turn has convoke. (Your creatures can help cast it. Each creature you tap while casting it pays for {1} or one mana of that creature's color.)
Doctor's companion (You can have two commanders if the other is the Doctor.)

Doctor Who

Although Doctor's companion is a new variant of the partner ability, the rules for partner have not otherwise changed. Notably, Time Lord Doctors and cards with Doctor's companion do not interact with cards which have another partner ability.

An effect that checks whether you control your commander is satisfied if you control one or both of your two commanders.

Both commanders start in the command zone, and the remaining 98 cards (or 58 cards in a Commander Draft game) of your deck are shuffled to become your library.

If something refers to your commander while you have two commanders, it refers to one of them of your choice. If you are instructed to perform an action on your commander (e.g. put it from the command zone into your hand due to Command Beacon), you choose one of your commanders at the time the effect happens.

If your Commander deck has two commanders, you can include only cards whose own color identities are also found in your commanders' combined color identities.

Once the game begins, your two commanders are tracked separately. If you cast one, you won't have to pay an additional {2} the first time you cast the other. A player loses the game after having been dealt 21 combat damage from any one of them, not from both of them combined.

The Doctor's companion ability allows you to have two commanders if one has the ability and the other is a legendary creature that is a Time Lord Doctor and has no other creature types. Creatures with the changeling ability, for example, can't be a second commander this way.

Because convoke isn't an alternative cost, it can be used in conjunction with alternative costs.

If a creature you control has a mana ability with {T} in the cost, activating that ability while casting a spell with convoke will result in the creature being tapped before you pay the spell's costs. You won't be able to tap it again for convoke. Similarly, if you sacrifice a creature to activate a mana ability while casting a spell with convoke, that creature won't be on the battlefield when you pay the spell's costs, so you won't be able to tap it for convoke.

Tapping a multicolored creature using convoke will pay for {1} or one mana of your choice of any of that creature's colors.

Tapping an untapped creature that's attacking or blocking to convoke a spell won't cause that creature to stop attacking or blocking.

When calculating a spell's total cost, include any alternative costs, additional costs, or anything else that increases or reduces the cost to cast the spell. Convoke applies after the total cost is calculated. Convoke doesn't change a spell's mana cost or mana value.

You can tap any untapped creature you control to convoke a spell, even one you haven't controlled continuously since the beginning of your most recent turn.
