Fantasma da Orquídea Branca

If the target land is an illegal target when White Orchid Phantom's last ability tries to resolve, it won't resolve and none of its effects will happen. That land's controller won't get to search for a basic land card.

If the target land isn't destroyed by White Orchid Phantom's last ability (perhaps because the land has indestructible), its controller still gets to search for a basic land card.
