Playing

Dream first hand swamp, Dark Ritual, and a Hypnotic Specter. If you dont get that just concentrate on knocking cards out of the opponents hand and using terrors and the Pillar Tombs of Aku to kill creatures while using Dance of the Dead (remember this can go into any graveyard) and bone harvests to get your creatures back
