Here's a cheap suicide black for ya...
4 Hypnotic Specter
4 Dauthi Marauder
4 Dauthi Slayer
4 Dauthi Horror
4 Unholy Strength
4 Endless Scream
4 Dark Ritual
4 Culling of the Weak
Start (hopefully) with a Dark Ritual. Get out a Dauthi (or even phage or
Hippie) and either Strength the Dauthi or Duress. Simple strategy: get out
many creatures as possible, power them up, and keep attacking before they
do anything bout it. 4-6 turn kill.
