"Find me cards equivalent to: Harbinger of the Seas"

Equivalent cards (same color, related effect):
1. Blood Moon — similar effect (lands become Mountains), but is red.
2. Magus of the Moon — similar effect, but red and not a Merfolk.
3. Spreading Seas — blue, turns one land into an Island, but only one.
4. Quicksilver Fountain — blue, slowly changes lands to Islands.

Closest pure blue equivalent is Quicksilver Fountain; none do exactly what Harbinger of the Seas does in blue and as a Merfolk.

  • 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 the first ability of 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 will lose any other land types and abilities they had. They will gain the land type Mountain and gain the ability "{T}: Add {R}."
  • This effect 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 "Mountain."

  • 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}."
