you splash for it because, especially if you're running 4 of it, there will be cases where you want to cast it. you don't plan on casting it, granted, but you want to be able to when it comes up that that is actually the play you need to make. if you're only running white for lingering souls and ray of revelation in a loam pox version, doesn't it make sense to just run one scrubland so that you can cast the front end when it comes up that you want to? same thing.
