It’s all about pumping up creatures. The big ones can be sacrificed to Bond of Agony for double duty. The vampiric component just works for the ongoing hurt. Nothing costs over three mana, so this should be a quick enough deck; however, it may need card draw capability, and that would mean adding Demonic Tutor, too. The 10/22/8 curve is wildly cheap, coming in at 1.95 average, but the Frozen Shade and Howl from Beyond cards increase those costs, allowing me to spend more later, when I can afford it.
