The trainer awoke to begin the journey from the wurm's tail to its head. The sun was setting when she arrived.

Die Bändigerin erwachte, um zur Reise von der Schwanzspitze des Wurms zu seinem Kopf aufzubrechen. Die Sonne ging unter, als sie endlich dort ankam.

Ureingesessener Wurm

Einberufen (Jede Kreatur, die du tappst, während du diesen Zauberspruch spielst, reduziert dessen Kosten um {1} oder um ein Mana der Farbe jener Kreatur.)
Verursacht Trampelschaden

La adiestradora se despertó y comenzó el viaje desde la cola de la sierpe hacia su cabeza. Cuando llegó, el sol se estaba poniendo.

Convocar (Cada criatura que gires al jugar este hechizo reduce su coste en {1} o en un maná del color de esa criatura.)
Arrolla.

L'instructrice se réveilla et entama le long périple séparant la queue de la guivre de sa tête. Elle arriva au soleil couchant.

Convocation (Chaque créature que vous engagez en jouant ce sort réduit son coût de {1} ou d'un mana de la couleur de cette créature.)
Piétinement

L'addestratrice si svegliò, pronta a cominciare il viaggio che dalla coda del wurm l'avrebbe condotta fino alla testa. Il sole stava già tramontando quando arrivò.

Wurm Aborigeno

Convocazione (Ciascuna creatura che TAPpi mentre giochi questa magia riduce il suo costo di {1} o di un mana del colore di quella creatura.)
Travolgere

訓練官は目覚めると、ワームの尾から頭までの旅を始めた。 着く頃には日が暮れていた。

土着のワーム

召集 （あなたがこの呪文をプレイする段階であなたがタップした各クリーチャーにつき、この呪文のコストはそのクリーチャーの色のマナ１点か{1}少なくなる。）
トランプル

A instrutora acordou para iniciar a viagem da cauda do vorme até sua cabeça. O sol estava se pondo quando ela chegou.

Vorme Autóctone

Convocar (Cada criatura que você vira ao jogar esta mágica reduz seu custo em {1} ou em um mana da cor daquela criatura.)
Atropelar

Наставница встала с зарей, чтобы начать путешествие от хвоста вурма до его головы. Она завершила свой путь на закате.

Первобытный вурм

Пробивающий удар

驯兽师醒来后，开始从亚龙的尾巴走向头部。 到了落日时分，她终于抵达目的地。

原生亚龙

召集（使用此咒语时，你每为它横置一个生物，便可以少支付{1}，或一点所横置生物颜色的法术力。）
践踏

Autochthon Wurm

Convoke (Your creatures can help cast this spell. Each creature you tap while casting this spell pays for {1} or one mana of that creature's color.)
Trample

Ravnica: City of Guilds

Convoke (Each creature you tap while playing this spell reduces its cost by {1} or by one mana of that creature's color.)
Trample

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.
