The way this deck works is basically like any other mono-black deck, to have multiple ways to win the game, either through overpowering with powerful creatures, or if the game is at a stall, through effect damage with cards like gray merchant, and whip of erebos, to keep bringing her back onto the field. My version has a few kill cards in it to limit the opponents field, which, in my casual play, I've found to have some good success. I'm mostly looking for suggestions to make the deck more competitive. I'm not looking to spend an absolute fortune, but I do enjoy playing modern, and I'd like to see what I can do with it given a few upgrades.
