Cleansing Wildfire — ruling 1

If the target land is an illegal target by the time Cleansing Wildfire tries to resolve, the spell doesn’t resolve. No player searches for a basic land card and you don’t draw a card. If the target is legal but not destroyed (most likely because it has indestructible), its controller does search for a basic land card and you do draw a card.
