I was messing around in trainer, and I randomly remembered that when a voodoo doll is poisoned, the opponent takes double damage. So I put a few bloodsuckers and voodoos in a deck to see how effective it could be, along with pests and vampires.
Then I tried it out against the AI. It did very well against AI3, but it would need healing for half-bloods. I thought about vampire daggers. 6 of them flying is faster and more quanta efficient than regular vampires. I put those in the deck in place of the pests with more pillars.
This is the result:

5 voodoo dolls and 4 dark pendulums, all upgraded.
I met with fairly good success in AI3 and AI5. With a good draw it can be very quick.
However, it is intended mostly for lulz. The animates at least have to be upped, but the rest can work unupped, even if a little slower and not as good against AI5 as the upped version.
A couple good cards to consider are siphon life and eclipse. Eclipse should be worked in somehow, but I'm not sure where.
