A landcycling ability lets you search for any card in your library with the stated land type. It doesn’t have to be a basic land.

Unlike the normal cycling ability, landcycling doesn’t allow you to draw a card. Instead, it lets you search your library for a land card of the specified land type, reveal it, put it into your hand, then shuffle your library.

You can choose to find any card with the appropriate land type, including nonbasic lands. You can also choose not to find a card, even if there is a land card with the appropriate type in your library.
