Frenzied Tilling rulings:
2013-01-24: If the target land is an illegal target when Frenzied Tilling tries to resolve, the spell won’t resolve and none of its effects will happen. You won’t search your library for a basic land card.
2004-10-04: Because the “search” requires you to find a card with certain characteristics, you don’t have to find the card if you don’t want to.
