This is a combo deck based around Rooftop Storm, Blood Artist, Grimgrin, Corpse-Born, and Gravecrawler. What the combo is that you have the four I mentioned on the field. Use Grimgrin's ability to sacrifice the Gravecrawler. The Artist's effect would go to the stack and do its damage. Then return the Gravecrawler to the field for 0 because of the Rooftop Storm. Rinse and repeat this process and you have an automatic win. Suggestions are wanted!
