The rising moon calls mercilessly to the waves, commanding the sea to rise high enough to devour mountains.

Unbarmherzig lockt der zunehmende Mond die Wellen und gebietet dem Meer, hoch genug zu steigen, um Gebirge zu verschlingen.

Vorbotin der Meere

L'impitoyable lune ascendante appelle les vagues, et ordonne à la mer de monter assez haut pour engloutir des montagnes.

Annonciateur des mers

月は昇りながら情け容赦なく波に呼びかけ、ゆうに山を呑み込める水位まで上げるよう海に命じた。

海の先駆け

基本でないすべての土地は島である。

月亮升起，召引浪潮接连来袭，使得海面不断攀升，淹没高山也不在话下。

海疆先兆师

Harbinger of the Seas

Modern Horizons 3

Modern Horizons 3 Promos

Harbinger of the Seas doesn't affect names or supertypes. It won't turn any land into a basic land or remove the legendary supertype from a legendary land, and the lands won't be named "Island."

If Harbinger of the Seas loses its abilities, it continues to turn nonbasic lands into Islands. This is because effects that change subtypes are applied before considering effects that remove abilities, regardless of the order in which those effects started.

If a nonbasic land has an ability that causes it to enter the battlefield tapped, it will lose that ability before it can apply. The same is also true of any other abilities that modify how a land enters the battlefield or apply "as" a land enters the battlefield, such as that of Vesuva or Cavern of Souls.

If a nonbasic land has an ability that triggers "when" it enters the battlefield, it will lose that ability before it can trigger.

Nonbasic lands lose any other land types and abilities they had. They gain the land type Island and gain the ability "{T}: Add {U}."
