Syr Konrad, the Grim presents us with an excellent opportunity for a combo kill. He triggers on just about anything a creature can do with the graveyard: dying, milling/discarding into it, and even leaving it.
Do you like R-Chupacabra? And getting caught in Notion Rain? OK, OK, Notion Rain isn't in this deck, but the Chup is, and so is Quasiduplicate, which means 12 opportunities minimum to 2-for-1 your opponent the easy way.
