I see that too as most of those kinds of players run a lot of fetchlands that will fetch red while the bloodstain mire fetches black as well as red the more the reason to toss in a few basic swamps as well as Badlands for the splash.
Soon I could see them throw in Green for the Korsan Grip Removal and if luck comes along an enemy Fetchland a will be circulated to give the decks more variation in fetching other kinds of basic lands as well as Duals.
