Core Set 2019 Promos

Alpine Moon’s effect doesn’t affect supertypes or other card types. It won’t remove the artifact card type from an artifact land or remove the legendary supertype from a legendary land.

If an affected land has an ability that causes it to enter the battlefield tapped, it will lose that ability before it applies. 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.

If an affected land has an ability that triggers “when” it enters the battlefield, it will lose that ability before it triggers.
