Question marks are upgraded Voodoo Dolls.
Strategy is to steal graveyards, antimatter vampires and get your voodoo dolls poisoned by retrovirii and bloodsuckers.
AI is smart enough not to target your voodoo dolls unless no other options are available however (still not smart enough to ignore them), so we don't steal graveyards or have other creatures.
It really does need a way to kill the graveyards however, so perhaps -3 siphon life, -3-5 obsidian towers, +4-6 explosion and +2 fire storm and change to fire mark. Once Eclipse comes out, Vampires will survive one fire storm while Elite Skeletons, Bloodsuckers and Retrovirii will die. Also, try not to antimatter before the first Eclipse comes out, because they'll end up with only -2 instead of -6. If Incarnate has only 1 Eclipse and you have used most of your 6 antimatters, you can explode the Eclipse to get -8 damage vampires (and 2 less damage from all other creatures) for a turn or two. Probably better to save it for a Vampire Dagger however.
