Skyclave Shade

After you cast Skyclave Shade from your graveyard, it's considered a new object, and the permission from its landfall ability won't apply to it again even if it returns to your graveyard later in the turn. You'll need to have another land enter the battlefield under your control after it has returned to your graveyard to cast it again.

Skyclave Shade's landfall ability triggers only if it's in your graveyard immediately after the land enters the battlefield.

You must follow the normal timing permissions and restrictions for Skyclave Shade when casting it with the permission of its landfall ability. You must pay its mana cost (or, if another effect allows, an alternative cost). You may pay its kicker cost when casting it this way.
