Control/board clear early game, if you curve your turn 4 Dreadsteed into a turn 5 Rivendare it's pretty much game over. You can mortal coil your dreadsteeds, sac pac them, whatever it takes to get 3-4 on the board. Then they never die and give you board presence after Nether, can be buffed with PO, buffed by Mal'Ganis, etc.
