Killed By Creature Sacrifice
Hope you get some 0 cost guys at the beginning and at least 1 Disciple and Ashnod's. Have your soul nets out, sacrifice the 0 cost guys to ashnod's for 2 colorless, opponent loses 1 life for each disciple on the field, use one mana to grim harvest him back, then play him, sac another to get more colorless, use a swamp to recover grim harvest, you still have 1 floating mana, pay 1 swamp to play grim harvest again, then repeat. Try to get gristle grinner out early, and then do this process over and over, to make gristle grinner a really high monster if you need to block.
