What the sac lands offer you if you can be bothered with all the shuffling and changing of life totals is a reduced chance to draw further lands, an extra boost towards threshold and fuel for your Lavamancer (if you are playing Geopede you should obviously play every sac land you can get to the point of playing things like Badlands and Blood Crypt simply to use off colour sac lands but this seems a little over the top for one card)
