Your play strategy should be to control the board and make value trades. We want to go wide and buff our board to eliminate the opponent. We can very easily go wide because of Galakrond, the Wretched invoke ability add 2 1/1 imps to the board. Then we can buff our board with cards like Fiendish Rites and Grim Rally There are other win conditions like Sea Giant that benefit from going wide also. I've included a video on the deck below. There is also a budget version of this deck that does really well on ladder as well.
